There are no worthwhile rewards, there is nothing behind AP, there is nothing that makes you go pvp or BG. Banal skins on skils would be a good start, or new motives that are new. It would be more interesting to play if on BG would fall motives that would fall only a certain time or some mini event in the imperial city or cyro (not 2x AP or telvar) but for example a big raid boss on the whole cyro or ic. More activity, more worthy rewards, more motivation.
