My major problem with Bodyguard is its lack on my mobility on its core abilities. Operative core abilities can be used on the move, same with sorcs. As for mercenary when channeling healing scan and advanced healing scan, your prone to stuns and interrupts, which then in turn makes keeping a dps alive all that much of a challenge, Another thing I would point out is that Bodyguard still has the weakest healing output. I wonder when that one is going to get addressed. Probably when the survival gets nurfed and only a handful of players are still playing Bodyguard.
