The lead designer of World of Warcraft posted an hint on the boards about the upcoming reward system for PvP to be added in the game:

Once we get the pvp reward/punishment system in, we will tone back the guard reinforcements in most areas.

My comment:
Ha! Finally hints about their plans.

This is quite obvious, I’d guess. I believe that this reward/punishment system will depend on the level range. So that ganking low level players will result in a punishment of some sort (like an exp hit) while killing one closer to your level will result in some sort of reward.

Still I fear that Blizzard won’t come up with a system really interesting and fun to play. I don’t believe that they’ll put many resource to develop this part enough since the main focus is about PvE content.

Eno, why noone talks about PvP *purpose* ?
I think this should be the main topic and a possible reward/punishment system should be just a part of a bigger plan where actions have some sort of meaning…
