Whenever I see players struggling in dungeon and trial, I always give them my tank mits, cover, or self heal to try and make them take less damage. Thats because I get it. When i first played the game I was probably worse than even the most casual players. Thats because I came from WoW doing strictly PvP so I was terrible in PvE mechanics and memorization, XIV is all about memorization of the dance.

It will get better as you get more used to it. And trust me when I say, mechanics in this game are not designed to be mastered in one go. What matters is trying again or check out guides if youre impatient. I was a very casual player for 2 years, raided only savage for 2 years after that, and now Im raiding ultimates. And yes I still died several times in Dawntrail dungeon and trial. Dont get frustrated, thats the key.
