i went for DH when the stars align (All the buffs) my full thrust is critting for 19k. usually in the first 30seconds to a minute of a fight i top the dps meters, as mechanics come into play and other classes hit their stride i fall back down to 3rdish depending on gear and class make up.

also with the new tombstone coming out next week (iirc) the BIS will change. there is some omega gear with no crit or dh on it right now.

i am using materia 5s since i have a ton but i wont go overboard trying to get 6s till we hit that point were gear wont be changing for a few months and its true BIS.
