Its already hard to kill ppl in this game with the zoning, 1/2 damage and lag. Could you please stop ppl from getting heals from ppl in 100% zone or 75%..
The best solution is to make heals team only, this will bring a little more balance into the game and allow people to fight. Make MP pet only heal ppl who are in your team. This is not only PvP relayed since a low level can easily kill higher lv mobs and gain alot of xp if a doctor is healing him w/out being in his team.
Kthxbye!
