I like that pve and pvp powers can operate differently. HOWEVER, they should still function very very closely so as to lessen the jarring experience of crossing over game systems.
PvPers new and old have to learn what amounts to an entirely different system to play pvp. In terms of making pvp more accessible to new players that is a non-starter, or epic fail if you will.
I liked (currently not subbed) arena options that let us cancel poor developer decisions. They have already been mentioned.
The speed of pvp and a full 3D environment (which is not utilized at all in pve) is what made this game attractive. Find a way to bring those aspects back to the forefront and you are set.
Pick a balance point and go for it. You can't be all things to all people. The old point was "balanced around a team" and honestly it wasn't far off the mark.
All my best to CoX,
