I don't know how anyone boxes any group in PvP without a shaman
Going to give it a try and see how it goes . While I see your point in the usefulness of tremor totem, I already have 2 shaman in each of my PvE groups. Even if they are a great PvP class, I really don't want another Shaman heavy group. I like the idea of a completely mobile kiting-style group for PvP.

I know there are going to be plenty of times people will get the jump on this group and cause some havoc, it's the fact that I can continue running around and ignore facing issues (while dotting up my opponent) that appeals to me with this group. When people drop fear bombs on me I'm just going to have to hope that I've already dropped 8-12 dots on them while I'm hopelessly running around. If not, I'll just have to use a recovery method or tip my hat to them for picking me apart. I can live with another opponent beating me ... I get frustrated when my inability to control the party (such as facing/following/etc) leads to my demise.
