EvE style server system with PvE and PvP server zones, but all one big universe. Think 1.0-.8 sec as PvE ie starter worlds .7-.3 sec as your leveling worlds and .2-0 as your full on PvP worlds ie Ilum...
Hey...I can dream right???
For those that don't know EvE, it's a full on PvP game in one universe, so if 50k people are on, they could conceivably interact with each other. Not suggesting ToR be full PvP tho, just the all one server idea.
