End Game version of 4 man Dungeons(mid-core content)

[Sylvain]

Sylvain, are you saying there are no signs of an impending attack by mobs in WoW's mythical dungeons?

no no, there is, I'm saying that there's a difference between the monster having a specific animation (even if it's super duper obvious) and puting a ginormous red mark on the ground telling you to GTFO.
I'm currently leveling various job and I've been through all Heavensward leveling dungeon many many time. I can see that player willingly don't ignore aoe and most of the time do their best to dodge. I also noticed that every aoe without the assistance of ground telegraph isn't dodged the vast majority of the time. The Aery is a great example. After the second boss, there's a dragon that has both a cleave an fireball that are clearly announced through animation. Most tank didn't dodge only these two skill from that single mob in the entire dungeon. They dodged absolutely everything else though. Same goes for NidHogg fireball which more often than not at least land on the player even though it is easily dodgable by simply looking at where nidhog face.

So here is my point, the ground telegraph makes everything much easier since, instead of actually paying attention to your surrounding and the monster's movement and animation, you lonly have to look for red mark on the ground.

If so then I would speculate that there is a small percentage of the player base that does them on a regular bases.

I'm not sure to understand what you're refering to here.

Side question: Do players feel they don't need CC in dungeons? Seems like I sometimes run into players that think so. Feel very disappointed.

Imo, CC as a whole must either be part of the game or not. Wow took the direction of making, for the beginning at least, a very important mechanic that is bordeline mandatory if your party don't have enough gear. FF made it 100% optional as only 2 job can effectively CC.
On a side note, I have the feeling that adding a mechanic like crowd control before pull, like in WoW, on the second expansion wouldn't be well received. There are plenty of other things that need to be adressed right now, and CC isn't an urgent one imo.
