Something I'd like to point out; it is really easy to get carried as a dps and people in the group, including yourself and other dps, don't realize it. If a tank underpreforms you see it by mobs not staying still, if a healer underpreforms you see it because people die. DPS can disappear in a group, not take their equal share of damage output and come out thinking they're good.

Titan HM is a good example of this. The soft DPS check is really generous. so people take the ability to dodge as the only requirement of the fight, and even go as far to call it a skill check and disregard gear. I've seen so many players who think they can do it because they can dodge, but they do it sacrificing too much dps and depend on other dps to carry them without realizing it. In my opinion a dps at the ilevel req would have to be doing optimal dps while dodging to meet the hard and soft checks, assuming all other dps are at the same level. This rarely ever happens, so you don't see this demonstrated. In titan EM though you do see it, and I feel its a flaw of the game design to let dps go this far into the end game before they hit a skill wall.

A good exmaple I had the other day was in garuda EM, we managed to clear it while carrying an absolutely terrible BLM dps who we were only able to call out on their lack of ability when someone was running a parser and noticed he was only doing 40% of the dps I was doing. Gear could only account for a fraction of that, and we passed anyway so even in garuda extreme BLM who don't even know how to output damage well are getting through. If that was a tank unable to play his class he would stand no chance.
