It's all the same to me, I don't have any skin in the game. I just wanna do what's the best damage (overall). I'm just saying that I didn't see how a spell that's predicated upon focusing a single mob would be better overall damage. Typically I run plenty of M+ during the week though, so I may as well give it a shot and see.

Cheze - Lol, TBH I'm so used to only thinking of Contagion/AC on that tier that I forgot about ELT. With regard to the corruption though, again uptime isn't what I was saying AC was good for. It's the bonus to each tick of corruption that I think is the argument in favor of using it.
