I see DRK as more of tank hybrid similar to the WAR. While I do see DRK being a possible dps I think that doesn't qualify in FFXIV. I mean our "Paladin" is really a "Knight" and not the traditional standard that all Paladins are supposed to be. I honestly prefer DRK to be a tank as it will add some more variety to the tank class and will help to alleviate some of the tank shortage issues. Do you really want more dps and longer que times? The DRK class is very popular so why not put it where it can do some good and get more people playing tanks.
