Just an FYI, Mage's blastwave also has a pushback, so I'd try to kill all mages before they can get into your group.

And as far as damage goes, my server had a steady 2k ms lag yesterday. My group is 4 shamans and a druid. I'll be able to see if the balance really is a noticable increase for my shamans. Also, I only spec'd 1 into ToW, so hopefully, that one stays alive longer then the others :-P
