Not sure you can do that...
Also, without massive farming set-up, there's no way anyone's getting the ubersaw soon. And without bots, you still have to play 150+ hours to get that.
(Seriously, you and a heavy with 30 kills, neither dying? 10 millions points healed?). The critzcrieg is debatably worse than regular uber, it's pretty situational, and so we're left with the needle gun.
And really, if a nocrit weapon which heals the medic as he uses it imbalances the game, I begin to wonder how fragile balance is. The ammo change likely had a similar effect.
(Ok, fine, I mostly play medic, therefore am biased
