Remove damage from movement skills

[Morningstar1337]

While I don't necessarily agree for corps-a-corps as it's more of an intended part of the RDM skill set than it is a gap closer, I actually generally agree with the topic. It really does feel like to maximize damage you're forced to use your gap closer skills when they're not really intended to be used just because of the damage they provide.

With Corps-a-corps, that issue could be fixed by gating it behind a mana requirement (with or without consuming mana, AFAIK the Enchanted combo uses 80 of both leaving 20 leftover if the bards were filled)
