I think, and if I'm wrong please correct me, but is the sync to the music of the second rocket on the spire clip just slightly off?

Aside from that it looks great. A lot of the syncing is really cool, but it might lose a little in the process. Ex: the house clip, the scout kills the demo and it skips to killing the soldier without any clue of if its the same life or a similar spot, etc.

I disagree with the idea of Rock-Paper-Scissors for the mediguns. It just... doesn't work that way in match play. It would if you assume that both teams are full uber with 6 up. And if you look at that as a situation, stock wins over Quick-Fix and Kritz, Kritz wins over Quick-Fix, and Quick-Fix jumps out and heals its players up because now they have advantage.

However, that is a small sample situation. The more important thing to note is how using each gun affects your team. Kritz is used to get advantage with the faster heal rate, and sniping medics before they get the full 100%. So in theory, Uber does counter Kritz, but Kritzing into a team that has Uber is always a dicey idea and speaks of a mistake in building or uber counting (which is possible, we're all human). So the question we should be asking in relation to the meta is what does Quick-Fix do to your team play in relation to stock? I'd say (but I'm bad so probably wrong) that Kritz makes you pop before they get theirs or risk getting destroyed if you have to delay.

*in which I answer my own question* In my observation, Quick-Fix's strength is in non-uber team fights. You always have better heals, and a generally more mobile combo (medic can jump and more efficiently heal the damage to pockets). But the downside is that you get fucked if they have an Uber/Kritz. It is hard to burst down a Quick-Fix Ubered medic+heal target, but the Quick-Fix can't position themselves in such a fight so they have to kite. So the effect of running Quick-Fix seems to be that teams running it have to pick fights off Uber with more importance placed on forcing bad pops and denying a medic charge.
