I'm signed up.

I'm pretty sure that the mod used in competitive matches gives you basic weapons and a very limited selection of perks/addons. If I remember correctly, I once played a match mod that gave each class Bandolier and Stopping power, and the only thing you could change was weapon and silencer.

Considering that the finals wouldn't be played on your own PC, it seems unlikely that they would allow unlockables. My guess is it's gonna be a match mod on the server (actually, i'm pretty certain it will be).

In which case, it doesn't matter about classes, we only need to decide who uses what weapon which we can do during training (lolz).
