As someone that used the Winger for alternate flank routes, this plugin just made it way worse than the default pistol. That roughly 1-2 seconds it adds to get anywhere is just not worth giving up all the firepower the stock pistol offers. From my experience playing Soldier, it barely ever was a problem except in one situation: you and the scout are low HP and he starts Winger jumping backwards while shooting you, which is still possible by the way. I think just make it do no damage at all. To stop the people abusing scripts, just make the swap back to other weapons slower instead, if that is even possible.
Gunboats always apply
I think this plugin is fine, but it definitely needs some adjusting. Before it was scouts torpedoing into soldiers so they kill themselves - now it's Soldiers going kamikaze mode, jumping onto people and point blanking them.
Med scout speed
It's too early to say anything about the flow of the game. Teams are inconsistent and still trying out a lot of stuff. The real test is W1 and W2. People will play more carefully in officials and that will show us how much the pace of the game has changed. Apart from that, it did nerf pocket scouts and focussed spam on doors is more powerful now because the medic can't walk in at mach 10. I don't mind this plugin at all, but I have to agree with klassy. I feel like playing a different TF2 than other regions doesn't makes sense long term, even if an international LAN is unlikely.
