For the small number of people using/thinking of using Linux: I thought I'd note that as of basically today you can run tankionline (flash) pretty seamlessly on Debian-based Linux distros by: Getting flash with "sudo apt install adobe-flashplugin" Installing Steam and running it in beta mode with Proton 5. Install and play tankionline through steam. (Also, be sure you've installed the correct nvidia drivers). If you have any further questions feel free to ask and I'll do my best to help out..

You would revert an item for parkour. Obiously.. Or maybe you'd want to revert m3 xpbp to have a completely fair match vs an m2 trash talker. I'm saying you should be able to revert anyhting if you like, but ofc still have the ability to go back to the highest M(1/2/3/4/5/6/7) that you bought for free.

Bruh why not just make it so u can roll back a upgrade if u want with no cost. But still be able to go back to M6 or M7 or whatever if ur done doing parkour.
