That thread seems to have a lot of interesting points... I've read stuff about 'creative' magic before, so to speak. I think it'd require players that understand what they want to do is subject to judgements moreso than usual.

And yeah, WoW is a game where you end up accepting that it's a fantasy game that aims at realism so little that you don't really think about it beyond basic things like: Mounts are faster than running. And 'Getting hit hurts.'
