The moment I used Bane and noticed that all the mobs in the huge pull got the debuffs rather than just 3-4 others my eyes lit up since I didn't read skill changes in the patch notes. Then I immediately checked the tool tip for Bane to confirm and was overjoyed!

Bane had been needing to work like this since day 1, and I am soooooo glad it does.

I can't quite comment on too many of the new skills yet since I'm only level 56. Tri-Disaster is awesome, but Ruin III on the other hand doesn't seem nearly as useful as the instant cast Ruin II, even if it does do slightly more damage and has a nifty animation. I can't, at this point see a reason to use it over Ruin II. Painflare is nice, it gives us more aoe options, but even so I find it hard to rely on it because it uses up Aetherflow stacks. Perhaps if I had more stacks of Aetherflow or the cooldown on Aetherflow was greatly reduced then I could see using this skill more often, but currently it's just one I use if I happen to feel like it and don't mind wasting an aetherflow stack that I could have used for Bane or Fester.

Maybe this will change at 58 and 60, but for now it's a little odd.
