Does anyone disagree with the assertion that even if Sonic is better target on boss fights, that you only spend a portion of your play time in combat engaged in fighting bosses? Anyone care to put some numbers to that--so that you're saying Sonic is x% better than (other power set) y% of the time, but the other 100%-y% of the time, Sonic is worse?
For a made up example, say Sonic is 30% more damage for two 5 minute boss fights over a 30 minute run. Is it the difference in beating the content or would you have won anyway--but you just saved 15 seconds--while the other 20 minutes may have gone faster with better AOE powers. And also having slows, -to hit, stuns, etc. might have their own subjective benefits. I don't have real test data to bear this out--wish I did, but I do think these questions are more relevant than trying to say Sonic is the wrong power to use vs bosses.
Anyway, I just posit that for future Defenders dropping by this forum that they don't all feel it's Sonic or bust, because many players feel the need to min max to what is "best", when the assumptions that said it were best were incorrect or the marginal benefit of that best vs the rest did not really amount to much. But I'm just a noob, so what do I know :)?
