From what I've seen, the animations are disabled on all Valve servers, even Casual. I just really like my custom animations and want to make sure Scrap.TF allows them.
I'm just gonna put my vote in:
- Randomizer
- x10 Mode
- Randomizer x10
- Medieval mode (other than Degroot Keep; x10 medieval mode is also fun)
- The Hidden (because I've never actually been able to find a working server with it)
And most importantly:
- Allow custom animations (darn Valve disabled them again)
