Serious question: how many would actually take advantage of said feature?
If asmos are that frustrated with the current pvp only they can fix the problem. They can always delete and reroll, or make a new account for elyos. But something tells me asmos don't want that.
I've even met few ely that are only leveling to feed their asmo account. Nothing like helping out someone only to learn they are just a feeder. Wont do bloodmarks, help zerg or pvp in anyway; just feed.
