You need to rethink how putting a set like unchained aggressor into the game... We are in a tank meta where people already build to survive you are now offering reliable major berserk to these same builds combines with something like onslaught you have now given them insane kill potential while being just as unkillable as they are this patch. Thanks to off-healing and how easy it is to stack % damage mitigation modifiers.. That isn't changing this patch which is what would've curved the tank meta all releasing this set does is give ball zergs and tanks major berserk for doing nothing, but eating a CC. It's lazy set design without any forethought on what it will do to pvp. If you want to put something that powerful as a set proc you better make darn sure it has some stringent proc conditions and it needs to be more than getting cced. It doesn't even make sense.
