I'll be honest, I'm not playing on a team right now so I've not scrimmed with the changes, only played a handful of pugs. But the medigun thing, while it's pretty broken is fairly unused. Most of the time if you are able to grab the gun it give you maybe 10%. It also solves a major tf2 problem that people have been complaining about for all time. It can make pushing out of last MUCH easier. If they enemy team pushes, your med dies at 50% but you still hold last, you now have advantage when your med spawns. In my opinion that's a bonus
edit:
yukiI personally wouldn't mind the medic thing too much if it worked like the vita saw i.e. you swap but only keep 20%.
I'd honestly prefer if the hat switching to keep uber thing was deleted - that pisses me off more to be honest.
This would make the same affect with pushing out of last that we have right now so I support this
