To put into analogy. . .
Soldiers have forced engage for pvp which gives 20% more critigation chance.
Healers have AA heal to help themselves survive better in pvp and their team-mates.
Mages have a damage taker for a few seconds.
Rogues have NOTHING. I tested FH on a mage and it DID NOT remove the damage barrier, and it didn't work on DT either (who had soul barrier). Who removed this ability form the rogues???
So basically rogues have NO free AA Archetype ability that can be used for pvp.
