My vote would definitely go to defender in this case. Sonic defenders (with vigilance solo buff) will pull even with sonic corrs, and of course will bring the much greater debuffs to the team
Forgot about vigilance hmm good point.
Actually if mids is to be believed cold has the same debuffs on both for some reason. The difference in sonic is huge though, and not having to wait til 35 for sleet is also huge. I'd go fendur too.
Thinking about making this pairing as I have an interesting concept. It could fit either class. How much damage would the defender do compared to the Corruptor? I know the defender gets much bigger -Res including the sonic which has an additional 5%.
Any suggestions?
