My suggestion for the past… Several years… Has been making all battlegrounds cross faction and adding in some sane group/role/ilvl balancing between teams.
I think that would be a much better solution. The idea should be to encourage players to participate in PvP by giving them better matches and feeling like their time is rewarded, not encouraging them to fight AI bots in a comp stomp type mode.
I explain this a little more here:
However I also think there should be a training mode/proving grounds type thing you can use to learn PvP and the maps and maybe earn some starter pieces of PvP gear to help new players not be at such a disadvantage when just starting, as well as conquest catchup mechanisms for alts or players who are behind.
