Aren't you full t6? :P
My guildies and me,all in t4 either conq or dt and we can solo tank any boss as long there is a healer that know his class,lucky for me i play with best pom in the game.
Killed 2nd boss with 2 only,me on dt and my guildie on pom,with him kiting/healing/dpsing,3rd boss for me is easier than the 2nd.
But well just my opinion,but my guildies and i are imba.
Not all about gear,but person behind the class.
Also i've seen t6 dts that die like paper,so i guess some people in raids just afk in a corner and loot t6 gear in the end it seems,which tells me t6 raid are easy as heck.
