With 1.2 coming.. I was curious about the multi-class buff that unlocks after leveling up other classes.

As of now on the test server, if you have a character that completed the second chapter in the class storyline, their buff is added onto your class buff. Does that also carryover to pvp? (Jump in pvp on my sorcerer.. use Mark of Power.. would it also give me 5% crit from my operative and 5% endurance from my mercenary?) or is it only in pve situations like the heroic ability?
