From their forums:
"The Origins staff are not opponents of customization, however, our goal is to make our server as live like as possible in the area of Realm vs Realm (RvR). For RvR purposes, we have selected patch 1.62 as the target patch. We want our Realm Abilities (RAs) to be true to patch 1.62. We want our class abilities to be true to 1.62. If you, our valued testers, find class abilities, or RAs or gear to NOT be true to patch 1.62, PLEASE DO REPORT IT!"
I actually might try Hib, because I never played there at ALL.
