why so much players have a rush mentality

[Y2K21]

Frankly, I cant tell if this anti-rush mentality is legitimate or just trolling anymore because the argument has turned into such a caricature of itself that it doesnt sound like real people in real scenarios. To me, usually I dont have a problem with going slow unless its a sprout tank or sprout healer. I'd rather they be comfortable with their job than being poke with a stick on to keep up with a veteran. That would also transition to new roles for veteran players (first time tank/healers). Outside of that, you better be pulling -- as you have no excuse.

Im sorry, but thats just the honest truth of it.

These experiences you speak of is something I have not seen in FFXIV. Perhaps you are thinking of WoW. That type of rudeness exists in Copious amounts over there.

You have so much to learn then.
