A friend and I decided to start some Ilum PvP a few days ago. We did so by attacking imperials, usually when there was 2 near each other so it would be somewhat fair.
How did the Imperials respond? They went to the top guild on Imp side, cried that we were breaking the "peace," then their GM went to my GM who then told us to stop attacking Imperials in Ilum(the pvp zone).
We said F that and kept attacking them, then got G-kicked for PvP'ing in a PvP zone.
Brilliant PvP zone design that pits faction vs faction in heated battle!
