- Not a bad idea honestly
- You can already do that. An in-game tutorial of some sort to explain server finder and custom map hosting would be nice. A tutorial in the first place would be nice...
- I'd personally be against padding hitboxes, but I get the argument. Muzzling slidehopping is a terrible idea; it's already done on the comp preset to encourage certain play styles, but it wouldn't fit in chaotic pub matches.
If you'd put these suggestions separately, I wouldn't have been forced to downvote your entire list because of one disagreement I had.
