rowrowThey originally quickbanned using this for mediguns, but now it applies to all weapons. Personally I think it should only be restricted to mediguns, since it'd be pretty meta to win a roamer fight against a black box user and then take it from him. That's pretty much the only place it can really change anything, and it's not game breaking.
They need to ban loose cannon, not this mechanic.
Banning everything could come from the fact that there is a Source Mod command to disable pickups, but it applies to all weapons rather than just mediguns. However, this argument would be useless if ESEA hasn't bothered to enable that command on their servers.
