Question about GW as it is

Is it possible for the GW1 engine to allow skill balancing for PvP seperately than PvE? I know GW2 is going to have pvp and pve seperatly balanced, so would it be possible in GW1? If so, maybe it'd be good practise for the GW team to start learning how to balance skills seperately.

Example, duplicate all the pvp skills for pvp balance and someone will only have those skills load in a district that people can meet for pvp? Maybe if you switch from pvp to pve and vice versa your bar clears.

Thousand dollar question: why same skills with same parameters are used in PvE and PvP, by monsters and by players?

The unlock system will have to be reworked or eliminated. Then what would heroes and tome use?
