There's gotta be a limit, just because of abuse of lower levels. Not everyone has guild mates or friends that can come retaliate.
With that said, 5 is just way too low. I realize boss drops aren't a thing right now, but when boss pvp eventually happens, whats the game plan? Someone goes from 5 possibles to murderer status in one AOE and loses their weapon?
It's Rohan - MR was the best buff ever because it allowed 24/7 pvp in the open world system. This is what set this game apart, and I'm disappointed it's not available in origin.
