We will not use any new spells as this is too controversial at the moment.
The "hotfix" however is a completely different matter, but only if it fixes something that before was broken. If anything beyond "vanilla" is added, then no, we will not use it.
I'm deciding this right here right now because I believe everyone involved really wants to play the game and not argue game balance. Hopefully you understand what I mean? If not voice your opinion and we can hopefully come to some understanding.
