"In any case we are continuing toward a goal of a PvP on/off toggle
for players on PvE realms to be added in Warlords of Draenor, which
would absolutely and in all situations allow someone to refrain from
becoming flagged regardless of their actions. Heals toward flagged
players would fail, coalescing to PvP realms wouldn't be possible,
misclicks and AoE's would never damage a flagged opponent, etc. It's
actually quite a bit of work because of all the systems involved, but
it's still something we think PvE players should have, and how the
game should work for them. "

Ok, I am celebrating right now, I have wanted that kind of thing for
so long - as someone who doesn't like to mix my pve and pvp, the
ability to never accidentally be flagged is perfect! Can't wait :-)
