The bonuses in the Ettenmoors need to be removed.
If you have all of the keeps, the Delving bosses and you stack on the store buff, you've got a 300%+ infamy/renown/commendation bonus.
That's all great and wonderful, except for one small detail.
If one side has a higher bonus, many players will "flip" to that side.
For example, last night the creeps on my server had the advantage in the Ettenmoors. They had all of the keeps and all of the Delving bosses, so that guaranteed that they had a minimum of a 200% bonus, if not more.
Unfortunately, it also meant that the Creeps outnumbered the Freeps nearly three to one.
This also happens when the Freeps have the higher bonus numbers as well.
So, as you can see, the bonuses are not creating the "balance" that the developers had intended in the Ettenmoors. It's creating an imbalance in the number of players, which, when you tack on the bonuses from the keeps and outposts, makes for a very poor game for the opposing side.
Also, FWIW, it has, basically, also turned the Ettenmoors into a "PvE zone" which a lot of PvP players are not happy with.
