Just wanted to give a congrats to Tripwire on Summer Showdown. It's about the most I've played Killing Floor 2 in a period and I've had the game since day one of early access. It started to feel like KF1 again, with the map objectives and rewards for completion. The introduction of the weeklies were a good surprise as well. I haven't been a fan of everything you guys have done with KF2, especially in regards to taking the exploitative Valve approach to lootboxes that only works due to the clout Valve has, but it was nice actually being able to just earn something in-game again. The faster drop timer had me playing more often, so I ended up getting Sharpshooter to max level and Gunslinger to level 20, I ended up getting about 50~ drops total, with 20 of them being crates (ugh) and 31 being tickets, including a golden ticket! Unfortunately I got the witch doctor hat three times in my ticket redemptions, but alas, it's an improvement.
I'll second Sini's sprint toggle suggestion, since there's no real penalty to having sprint held down at all times anyway so there might as well be an always sprint option.
Another thing is to loosen up cosmetic compatibilities -- in fact, I'd say just remove the restrictions altogether since there's already a well known means of working around it to use incompatible ones together anyway, this'll just be much more convenient.
