Then, our 4-set bonus, where we can cast AC on the run. I do almost nothing but pvp and I can tell you I haven't used it once yet. We cycle fast enough, it's better to hard cast _fast_ and do damage to get to the next eclipse which happens fairly fast if I'm not focused.
Look at the other dps pvp set bonuses. Ours are just terrible in comparison.
We've been asking for years for a defensive capability -- like making Owlkin Frenzy something we can proc or be useful. We can't get into bear if we're stunned, although making Ursoc's Might instant has helped somewhat.
