Honestly, OP, your English isn't bad, but in truth you didn't offer any suggestions. You just keep focusing on how it isn't like XI, or caters to much to X playerbase, but you weren't able to reveal how something like "Combat Skill" could fit into XIV, or fit into a game without feeling like a grind.

Combat Skill which in essence is "horizontal progression" of leveling a character is pretty much the same mindset as Yokai FATE farming. Mindless content beating up the same creature/repeating the same FATE in hopes of RNG gracing you with what you are hoping for.

Now let's go to the longevity of content. XIV content doesn't have the same longevity as XI for good reasons, because XIV doesn't lock you out of Dynamis for 3.5 days(now daily. . . but still Daily), and every other content released in XI had daily limits, or the need to farm for 12hrs yes 12hrs waiting for timed NMs that you had to fight with others against in hopes of being able to get the drop you want.

XIV cuts out all that fat, what players think they miss are those moments of just doing nothing but waiting for something to spawn, or fighting others for a spawn and getting nothing out of it for waiting 5hrs. But it was honestly cheap mechanics used to increase the longevity of content.

What people think they miss from other MMO, they would actually be coming back and saying how "it's to much grind." "I don't have time to wait this much." "This needs to be faster." "We need more options to get loot that aren't RNG" etc etc. People think they miss the stuff from older MMOs and they think newer MMOs are the bane of existence.

But sadly it's hard to have a successful horizontal concept in an MMO, unless you just made it part of PVP or another part of the game that didn't force people to play that way. It's just hard to execute. because at the end of the day, I"d rather have to go through VU phases of regearing my job to be stronger again than to have to spend 6 months trying to get a piece of gear that came when the game first went live because it's a 36hr spawn with a 2% drop rate and there are at least 10 other people I"m camping against in hope of getting the drop and in the 2 weeks I"ve been trying on and off I haven't even been able to claim it. That isn't fun, but people thought that was fun. Isn't it more fun to actually play the game with what the developers introduce into the game instead of the metagame of wasted time camping and fighting against others in an artificial PVP setting?
