So I just got SMN to 70 on the alt I use to play with my husband, and I've been using Bane in the Expert roulette for big pulls. Then I w as criticized for it, and told that the massive falloff on it makes it a useless skill I shouldn't even have on my bar. I was told that I should be manually cycling through each enemy in a pull and applying the dots that way, even if it's 15 enemies.

Please, help a confused SMN out! I'm not a hard core raider, I'll do extreme trials and such but generally don't go into Savage content. But I would like to make the most of my damage output. So if someone could explain to me what I should be doing for big mob pulls I'd greatly appreciate it!
