There was a similar problem in pvp a while back for a different mmo i won't bother to name.
The solution was as simple as adjusting the "lore" so that the battlefield was now a "Training Simulation" or something of that nature.
It doesn't have to be Shakespeare, just make up some quick crap so that gameplay can be better.
This, to me, is even more important to this mmo because it would help offset the natural bias towards certain classes that the different GC's tend to have for the most part.
