My initial thoughts on that are in pvp it would hurt more than pve, I don't get much rage from SR as I do from raid bosses pounding me. :) so I dunno, maybe not so much in pve but I can see it hurting a bit in pvp. It does seem they built SM around the fact they expected us to use SR so, one would think they'd have to do something.......right? I hope.
Still want my shield bash back. ;)
