The 8th stage of the annual John Van Caneghem Tournament (2007).

Actually, the rules state that it is not allowed to revive fallen heroes without any distinction between allies and enemies.

If this issue hadn't been discussed in detail before, and if a decision on how exactly to interpret this rule hadn't already been made, I would agree with your statement. But I can't, because a decision has already been made. I hope it's final.

Otherwise, we have to acknowledge that it has become the norm for us to change the rules during the game... That's not good. :)
