Yeah, for a healer, sure. I wonder if it would also help with my channeled Force Lightning (Sorcerer)? It's channeled for 3 secs and does a total of like 700 damage over that 3 secs (at my current level). If I got Alacrity points so that it took less time to channel, would it still do that same 700 damage, just in the shorter time?
Still, I suspect that Power would be more useful than Alacrity in that case.
