I second this. If anything they should do a respect for all character simply because your build may be dependent on other players builds. For instance if a power changes in pvp to be better or worse then an opposing player may want to change their build to account for the other players changing their builds. If something effects a healer to be worse then a tank may want to change their build to be more sturdy to compensate for that. TLDR version respecs are needed not just for the ones effected by the buffs and nerfs but those indirectly effected by them in pve and pvp.
