I actually have am Ill/Sonic Controller.
In some ways, the pairing works better than with Force Fields.
I mean, you can debuff the enemies Resistance so the PA will actually manage to do more damage.
That is something that Force Field can't do.
So, there is at least one power that can benefit the un-buffable PA, unlike FF.
But, I do like being able to keep multiple bosses flopping in a corner with Repulsion Field, Force Bolt, and Air Superiority.
And when a Paragon Protector boss is flopping, they're not Mogging. (or snogging)
