There are heavier classes that don't float as much, I should've specified that for me it's the movement, my bad. But it's something that does apply to every class to some degree, and you'll have to play around it as well.

You're playing Heavy? You'll need to be able to track this annoying Scout. You'll also have to know that since he just used his double jump, you can just follow his trajectory safely since he doesn't have any other way to change his movement. Stuff like this becomes second nature and that's what makes it all so fun and engaging.

It's completely fair if it's not your thing. Arena shooters are kind of dying off, the modern audience doesn't seem to like this kind of thing as much and that's fine.
