Well, we don't mind if you have Imperial characters... we just want you to be in only Pax, no other guild. We want players that want to join our family overall, not just looking for a guild tag to put on their heads. So, you're Sith would be welcome in our Sith alt guild.
Yeah, as much as I would love to join PAX, I can't abandon my guild on the Imperial side. Even though we have a select few hard core PvPers, we are not really a PvP guild, and most of the people who were in on running HM EC have abandoned the game for GW2, but the core players are still there and a great group of men and women.
If you ever decide to make an exception to that rule, let me know. I have an upcoming Shaodw that would fit your ranks very nicely.
