Yes! Absolutely!
I get that part of Rohan's appeal is it's totally unregulated, open world pvp. It is also one of its biggest curses for those that really prefer to pve/farm in peace without rampant rpk just because there are tensions between a couple guilds. It will mean those that have AOEs will need to be careful that they are only killing their 'enemy' guild members and not random others that have nothing to do with the battle.
Personally I see this whole get guilds together and battle it out with no fear of murder status & need for MR as a really good thing.
It will also make those doing that random 'testing' thing a lot more careful.
