I really like the changes and I think it was worth the wait. We got massively changed mechanics for pyro flames, afterburn and airblast which make them more skill based and consistent. Then we got 4 unlocks which are clearly going to change the metagame for pyro.
The balance changes are a really good step in the right direction and they get rid of a lot of annoyances and lots of outliers in the wacky balance of TF2.
I really love the new contracts system and the skin changes, as well as how you can inspect all weapons now.
The quality of life improvements to casual, cases and just in general (like the model breaking and the bug fixes) were a nice touch.
This update was much bigger than gun mettle, meet your match or tough break, so I'm happy.
Hopefully the TF team has something in store for Scream Fortress and Smissmas as well to surprise us.
