Can we make it so every champion can cheese level 2...

If you get all-in deleted at lv2, you did something really wrong. Dont do whatever you did.

Most 'cheese' attempts have a pretty big opportunity cost, so if you anticipate the potential of it and avoid it, then you end up with the advantage.

I'd be wary of differentiating between 'cheese' and people simply using their level 2 advantage or similar tactics though. A jungler invading at level 2 is probably not cheese, purple side bot lane waiting in blue sides tribush to ambush them post leash (instead of leashing/getting early lane shove) is.

Try playing smarter. I get it, that's sort of hard for you. But you'll never get better if you don't try.
