I was thinking and analyzing my thoughts for a bit and my conclusion from that is to add something like a Jump-perk. So basically we will add the perk to the shop, that perk will be usable in all gamemodes of the Mix server and will only be usable once per map, just like the reroll perk. I know, sounds crazy doesn't it? But think about it for a bit, it wouldn't be OP in my opinion, it can bring more entertainment to CTF for example where you can outplay people by being able to jump. It can be usable in NTS to avoid rams for example. Whats negative about this perk?: Well, it may cause some shortcutting in some maps, but hey there are already thousands of shortcuts in our Mix maps isn't it?
Edit: I forgot to say, feel free to share your own suggestions and thoughts about this kind of perk
