Last night was my first time doing Ilum battles, and man..........it was a lagfest. I believe all in all there were around 50-60 people in the same area, and I had issues trying to target people. This is definately something that needs to be addressed, but I don't think it's gamebreaking imo. I still enjoy the game. I even turned down my settings to low to see if it would make a difference, but nope.
