Seriously considering dropping Pain for Sonic Boom. Am I stupid?

[bronislav84]

I'm level 36 with 8 points free. I'm not a DPS Engineer.

I have the usual skills, hate Leech and Wither, and don't want to invest on skills that don't factor into my playstyle. No extras, at least until skill flipping is done away with (which seems like it won't ever happen).

I have a point in Pain and a point in Force Shield. While I use the shield for the extra regen quite often, I find stuff to either be immune to Pain (bosses) or die too quickly to have an effect (everything else). Maybe I should drop Pain entirely?

6 in Empathy, 6 in Protection, 6 in Transference, 6 Decay, and 1 in Res rounds out the rest.

So what are people's opinions on Sonic Boom? We all know the cooldown is atrocious, but I know I'll be using it every chance I get. If I get it. It would be so much better if it could be used more often, like Transference.
