And not just targeting and maintaining lock on enemies... healing allies is also a hit-or-miss affair; I go to heal an ally, lock disappears and I waste a heal on myself.
Oh I hate that with my sci. Usually I'm quite capable of tanking ground stuff with her, once in a while I try to heal others who have aggro, to be save.
Then I suddenly change targets the second I push buttons, wasting heals on wrong targets...
Same for Space, it hardly makes fun flying a healboat atm.
