Its will never happen, aiding a red in town will ALWAYS get you whacked by guards. Healing of reds in town will lead to more ganking then there is already.

Red and don't like it? Then why you go red....
The order/chaos stones are there for a reason.

Don't want the chance of getting whacked for your actions then stay the hell out of guarded towns and factions are coming soon.

I'm trying to encourge more players to leave town and since I let reds in it seems to have worked. I see alot more blue players outside guard zones and an incress in pvp (even though the pvp is mostly in the center of town instead of the gates of town).
