I'd hold your welcomes for a bit until we see what actually happens. I don't think a few people among the staff will be happy to hear from me again if you know what I mean.
I think the MA will get denied. You can't be a master at all those magics. It's just powergaming, under the current rules.
If anyone else came and tried to do get accepted as a master of 5 magics and an expert of 1 they would be denied, regardless of how staff feels of them.
