To be honest. Warhammer T4 pvp was some of the most enjoyable PVP ive played. Massive, memorable battles are what Open world PVP is all about.
But for it to bleed over correctly into TOR, there needs to be some Incentive to actually "win" the zone. Perhaps some kind of WZ/Merc comm's increase buff when in posession of Ilum?
Could put the same lock timers into Ilum as with the zone locks in WH.
This wouldnt help the imblance issues one single bit I know, but please try to understand that NOTHING with regards to Ilum will change the faction imblance.
