South Africa here. :P.
Have been thinking about the technicalities and valve would need to update whitelists so re-skins are covered by a single item in the whitelist, and if banning stock items is allowed, then that has to be added to the whitelists too. Nothing really complex though.
Is anyone interested in writing a script for this in the mean time?
Also, I think the new changes to the game that would be possible if banning stock items was included would be amazing, with the banning of medi guns or sticky launchers totally changing how the maps would play out.
I am more a 6v6 person, but I think any interest from Valve is a huge plus for the worldwide community, when it comes to getting people interested in competitive tf2.
