I was playing a Necro/FF on Redside. I liked how Repulsion Field felt. I had a couple of "oh no" moments, popped Repulsion Field, and watched my minions do their thing.
The same thing happened with Dampening Bubble. I was trying to figure out if I had any suggestions for it, when I was suddenly surrounded. Popped Dampening Bubble, minions did clean up, before I could even thing of turning Repulsion Field on.
I can see how I could invest more recharge into it, though it still won't become an "every pack" kind of thing. I'm ok with that.
I am curious how it will perform on some of the other FF characters I have. With Necro MM, I didn't have a need for Force Bolt or Force Bomb.
