I started a conq 1 month ago to test it by myself, here are my conclusions:
In carnage, at pvp 3 with nothing of pvp, just pve t1 some t2 and t2 weapons was killing:
-Rangers pvp 10
-Sins pvp 8
-Dts pvp 6
-Guards pvp 7
-Barbarians pvp 10
Except good bear shamans and mages (Necros, demons, Hox), due to 0 protection and only 1 antiCC it is almost imposible, only able to kill low skilled trash pvp 5 or less.
And i still have no:
-Cloak (Green of 50 health)
-Necklace
-Weapons with crit rating
In brute with bubbles minigames is just a "pick and run", able to run in blood ravine from enemy base to yours with security of "im not going to die here".
Basically, with all theese notes, i confirm this class is broken. Last thursday in khemi arena dueling vs DT pvp 7 (full mini + ibis + waning boundary), beated him in brute like np.
A solution to the class would be increasing time between bubbles... bigger damage penalty in defensive stance, or set all combos to 2-3 keys, no 1 key combos.
As delred said their dps is insane for a soldier class, my little bastar* conq in less than 1 month has more dps than my 3 years barb pvp 9, ranger pvp 7 or sin pvp 5.
Since i like chalenges, i'm returning Barb with the new pvp patch.
Sorry for my bad english, still studying it.
