I've been fussing over what level 20 power to take - am mostly ice, with regen, force shield... - and was going to go with frost breath (for the sheer joy of it) when I saw telekinetic eruption.

Wow - that seems like a great get out of dodge power with its knockback. It seems like it could be great for pvp, but how does it stack up in pratice?

Also, what are the other best pvp knockback powers. There is one, seems to be single target, that always sends me flying and sprawling. Could also be useful, I was thinking...
