Gemmellnessyou could also wait a week for people to stop using the new weps
I doubt it, jarate and the loch and load are extremely viable options and I don't see people reverting back after trying them out.
just because they are new doesn't mean that people will try them out and throw them away, competitive players are pretty good at adapting to new and better options, although they rather not have them allowed if it means the game becomes less fun to play.
