I don't think I agree with removing totems although I think they should tone down the early limit of totems but that would increase based on Summoner level (and be more noticeable if it does already)
I do think that Dimension Bolt needs a change though, maybe instead of dealing random elemental damage and creating that surface it will deal elemental damage depending on the surface the target (or the user, which could potentially give a use to Elemental Affinity) is standing on. Would work with how Incarnate and Totem summoning on a surface works.
