Do we know anything about what happens when a neutral player is healing, rezzing or buffing players engaged in guild or node war combat?
Guild wars don't use the flagging system, so, as an example, let's say guild A has a group of 7 and need a healer, so they pick up random healer X and venture into a dungeon. Guild B happens to have the same problem with lack of healers, and they pick up random healer Y and venture into the same dungeon.
Guild A and guild B are at war, so of course they start fighting each other. As for both random healer X and Y, all they are seeing are a bunch of non-combatants duking it out, because only the guild members see the enemy guild as enemies.
So what happens? Are the two neutral healers allowed to heal and rez indiscriminately? If so, this could force the members of the other group to flag up and get corruption for killing that neutral healer. They might win the fight without killing the healer, but unless proper mechanics are in place, there is nothing stopping that healer from rezzing the dead party members.
Any system that can be gamed, will be gamed. Especially in PvP. So I have many thoughts and suggestions, but if it has already been addressed somewhere, I want to see that first
