hehe I guess I'll be the same when the expansion hits :)
Assuming I'm still playing etc (and my interest in WoW continues unabated at the moment) I'll be updating this for the expansion. Currently I'm a little confused by all the changes being made and not entirely sure which ones will affect MageFu. Will all the spell casting stuff prevent conjuring/portals/teleports by clicking on the menu items for example? If so is there any way round this? I guess if I find answers and solutions to questions/problems like these then I will pre emptively fix them before the expansion. It's certainly not my main priority though as I stated before.
AFAIK most of the "changes" effect in combat only. You might have to make small changes for out of combat casting but the major changes are for in combat stuff so eating/drinking/portals etc which are all done OOC shouldn't be effected very much at all.
