+1 for disabling awakes.
+1 for disabling haste sets, I mean those speed buffs in the pvp zone are there for a reason.
And while you are at it disable loud-outs in PVP as well.

Please do it for a week, I am sure it will be insightful for pvp balance.

If you are worried about the revenue from awakes then here is a longer solution:
1) Make PVP specific gear and disable all PVE gear from PVP zone.
2) Make PVP specific awakes for PVP gear but only give 2 awakening slots.
3) PVP awakes should not be overpowering, for comparison they should be like jewels; A player with full noble jewel will have lower stats than a player with full precise but its not game changing. I mean we have variables like (min-max) skill damage, crit chance, buff/debuff, pets, etc., to take care of that.
