Just because Valve re-balanced a weapon, it doesn't mean they did a good job of it. As someone mentioned earlier in the thread, they buffed Quick Fix a couple times before they actually resolved its main issue (no overheal) along with a couple other stupid changes. They need to revoke a couple of them (capping/medic overheal while ubered and no knockback) and it is feasible. In its current form, it's simply the Vita Saw scenario once again - if you don't use it then you're at a disadvantage.
One other thing - it's obvious that the Gullywash game between HRG and mixup was by far the worst stalemate-fest, but other matches/maps were also pretty bad (Granary, Metalworks last and some Process). It wasn't just waiting for things to happen which bored me, but it was also the 'uber vs. uber' fights which I could barely follow and just seemed like a complete mess most of the time. It felt like 2 teams just running into each other and hoping for the best. I've no doubt some may disagree on this, but as a spectator this is how I perceived it, and quite honestly it was like watching Soap DM in several cases. Some of it is down to underdeveloped meta on dealing with Quick Fix, but I'd much prefer it when there's a bigger risk/reward for Medics on when and how to use their ubers.
