We'll likely get only 1 or 2 actual full on new skills so I wouldnt worry too much, most of which should fill in some missing skills, "aoe version of this, single target version that" kind of deal. Also likely the rest of the EW skills are just upgrades/passives for existing skills. Yet to run into a serious button bloat problems for controller, and I just use 2 crossbars and 1/2 a crossbar for the L+R/R+L (made them both go to same crossbar 1/2).
