If the Quick-Fix plays as badly as so many here say, doesn't it follow that, like the Atomizer and B.A.S.E. Jumper, it will probably be banned before the league seasons begin? It seems to me that the best thing to do, if you hold such a view, is to test it as much as possible. Then, at the next meeting, you can come forward and say, "We have used this thing in x scrims. It has detrimental effects a, b, and c. We want it banned (plus whatever other arguments there are to make)." This would counter those who want the Quick-Fix unbanned; those who support it almost certainly would argue that both it and the game have changed sufficiently since 2013 to make it good for the game. If you can show that this is not the case, then it seems to me that rebanning it would not be difficult to achieve.
Incidentally, I may have missed it, but was there a reason for this meeting taking place yesterday, rather than, say, mid-December, before Christmas and after fall semester (assuming institutions in Europe and Australia also finish up semesters in early December; perhaps they do it differently)? That would have provided much more time to test things, wouldn't affect Rewind LAN, and would be easily resolved before the seasons begin. This isn't to bash anyone; I just wonder what caused the late date.
