Adding NPC's to Ilum doesn't sound like PVP improvements to me. Adding a bunch of gathering mats and PVE quests to the zone also doesn't seem like an improvement. Sorry OP but I don't see how they'd improve Ilum.
I'm on Ajunta Pall too and have teamed up with Coba many times. Ilum does have FPS issues, unlike other zones, so I do hope performance improvements are inbound.
LOL, no Ajunta Pall is not a "Republic Dominant" server. There are many more Imperial than Repbulic players on Ajunta Pall. We're 99% underdog on Ilum, usually about 2:1 odds.
