The game is cake leading up to Titan HM. Once you hit him and beyond, everything is a gear, reaction speed and eventually coordination check. As intended. I mean, every server is using pick up groups to occasionally successfully clear parts of coil, so it's pretty clear that there's nothing excessively difficult about the game.

That said, you lose some credibility when you play the easiest damage dealing class. You are literally the least important person regarding the success of nearly every encounter.
