I chose BRD for swift gameplay, if I wanted to cast I would have chosen a Mage.

An action can be silly and immature but not bother someone. If I saw you walking down the street jumping and spinning 360s for no apparent reason, I would probably laugh, then assume something was wrong with you, but it wouldn't offend or bother me.

People, you heard it. Better stop jumping because it's not what mature people do whilst fighting dragons on the streets!

In short terms, you would rather have bad gameplay habits than being forced to stay put, otherwise you would find the game "so bloody slooooooooow and booooooooooooooring"?

Can I ask why do you even play this game if jumping around is the only thing that keeps you awake?
... Or is your name Barry Allen? Do you have Sonic the Hedgehog posters all over your room and your motto is "gotta go fast?"

Oh man, I have so many questions now.

First of all, nothing about moving when there's time to move is a bad gameplay habit. In this game it's very easy to do whilst executing a rotation, considering it's a whopping 2.5 second window during an instant cast. In some games moving is vital for survival. For example, you know, any fast paced pvp game. If you claim that it causes people to play poorly, then I'm sorry to say, but that's just you projecting your own inability to judge situations and multitask onto others. Plenty of players can move and jump around occasionally while doing their rotation perfectly. Secondly, no one will ever force me to what I don't want to do in a game I'm paying to access. So the notion of being forced to stay put is a bit amusing to me. To answer your question though, yes, I'd rather keep my preferred playstyle than play something that bores me to the brink of sleep. If this game removes all instant casts and makes all classes so slow paced my granny could handle the rotations, I will be directing my monthly payments to another company.

Since you are so interested about my reasons for playing this game, I took the time to find my review on this game. I hope it answers all of your questions.

Details, first impression: 9/10 Game starts a little slow but hooks you after a while. They have put a lot of attention to detail, especially NPC dialog.

Graphics: 7/10 The art style is amazing, but on the technical side the graphics are quite hard on the pc so I have to keep them low.

Questing: 10/10 Interesting story that actually gives you tangible rewards like new content and faster travel. Plenty of sidequests that also sometimes give nice rewards. The leve system is kind of like daily quests which you can store for later, so there's plenty to do even on alts. Having unique quests for each class is a big plus for me.

Classes: 7/10 Some of them are a bit slow especially during low levels. All of them are good at their role while also being distinct from other jobs. The armory system is nice for people who want to play only one character. Some jobs had some odd additions in Heavensward and that drops my rating a little.

Dungeons: 8/10 Level sync and roulettes ensure every dungeon stays relevant, this is really nice. Low level dungeons are done very well because they get gradually harder and can't be mass pulled from start to finish. Level 50 ones are too easy because the item level sync is too high. Some dungeons have annoying gimmicks like cannons, which I personally don't like. I want to play my character and not a vehicle. :P

Raiding: ?/10 Haven't tried.

Music: 8/10 Battle music should be able to be toggled imo. Some tracks are a bit simple but most of them are good and do put you in a certain mood that suits the area. Heavensward did music better than ARR.

Crafting, gathering: 10/10 You need a combination of luck, knowledge of rotations, gear and patience. It's challenging, time consuming and most importantly rewarding, and it also encourages exchanging things with other players with a different crafting focus. In other words it's a complete end game of it's own and is also completely optional. Perfect.

Flying implementation: 9/10 Good overall, but I wish they had added a different quest marker for the required side quests. I also wish you could fly straight up but I guess it's more realistic this way.

Community: 8/10 The in game community is very helpful and people usually take wipes and mistakes well. Can't really say anything about the raiding community. Commendations are a nice thing to have. Sometimes people are a bit quiet though, and there isn't really a continuing chat going on in cities. Linkshells are used for in game events on some servers, and there are some events on the forums too, for example Eorzea's next top model competition.

And to add a few things...
Glamour/mounts/pets/titles i.e. vanity stuff: 9/10 There are so many of them only after 2 years! It keeps collector people busy for a long time. However, there could be a bit more unique mounts instead of reskinned chocobos and ponies. Glamour restrictions (gender, armor type) could be less strict.

Housing: 4/10 Beautiful housing wards, so many furniture options and even gameplay (garden, chocobo stable). All of this is unreachable for the majority of the player base because it's not instanced. Quite a big disappointment in that sense. I hope that once I get enough gil for a big house they have added more wards.

Dailies, weeklies: 8/10 Beast tribes, roulettes, Cactpot, hunts, leves, GC turn-ins and challenge log all give nice rewards and combined they can fill up your play time quite well. They are mostly used for gearing and leveling up, and I hope they add more repeatable stuff for vanity in the future.

Overall rating: 8/10 Great game! Worthwhile money and time investment even though some small things could be improved a bit.

Edit.

Okay, I'll rephrase.

Sure, I'll rephrase too.

Jumping around not caring about the other's positions,

Never said I don't care about others' positions, you are just projecting your own inability to do so whilst moving.

wasting MP casting Ruin II instead of Ruin I when possible,

Read carefully, I said I use it when weaving ogcd. They have a short delay so if I need to use two in a row it's better to cast Ruin II and then utilize the gcd, instead of wasting the length of a gcd on ogcd abilities. Number 1 rule of dps: always be casting.

not DPSing as a healer when given the opportunity,

When I cba means when it won't make a difference, for example the last moments of a trash pull or when melee is about to vaporize the boss with limit break.

moving around the boss dangerously and increase the risks of taking a cleave or missing an AA,

Projecting again. Just because you're careless and might do those things, others won't necessarily.

doing 360-flash-noscope thingy and not positioning ourself well enough to get block and parry procs...

Can't block them all anyway on the first couple of seconds on those certain pulls, where mobs come from every direction after you aggro one. Flash 1 just as they reach you (this is where you can do your dance moves), Flash 2 when you have moved so they are all on one side. It's all situational.

yeah, in 4-man dungeons, it's fine.

Happy we agree! I hope you are not making assumptions of my play skills based on my achievements on this game, because that would be quite a superficial basis for judgement. Other raiding games with more fluid gameplay, less lag and similar mechanics exist you know.

FFXIV is not a PvP game however. It's a team-rope-jumping PvE game

Oh I know. Nothing you've said so far points that a mobile playstyle of someone, who can tell the appropriate situations to move, would be a hindrance on the team. Especially on a class that was originally designed to be mobile. Your whole "bad play habit" argument is moot because a skilled player will never suffer for jumping around in this game.
