World PVP can't really be revived until the game engine is optimized. The biggest problem with Ilum IMO (other than the faction imbalance) was that when more than 20+ people were in the same area fighting/AOEing, the game turns into a slideshow.
I can deal with pvp lightsabers being un-moddable, but can we please at least have the option to change the color, at least on battlemaster sabers? Even having the option to change the core color to white. These black sabers are lame and fugly.
This is the problem. I could maybe understand if I was getting terrible FPS on Ilum and my CPU/GPU were being pushed to their limits, but they just aren't. Not even close.
