Suggestion from a laner: Don't nerf jungle exp gain, instead work on tooth and nail

Also I believe scuttle patch could be reverted. Here is the reasoning:

Jungle advatange doesn't come from exp gain, nor even from early ganks.

Jungle advantage comes from unavoidable differences in skill levels of players in every match. If a good jungler observers a skill difference in one of lanes, they can do a lot of things to equalize it, or extend it if it's in their favour.

Meanwhile, if a good laner observes skill difference in the jungle, they can do very little with it. Not like nothing, but every play around the map comes at a much greater cost and effort to the laner. Abusing bad enemy jungler or enabling a strong one is not impossible, but it does yield much worse results - to over-simplify things, a jungler can camp a laner, but a a laner can't camp the jungler.

Unpopular opinion: in infamous scuttle patch Riot correctly recognized this problem and tried to give laners a way to slow down enemy junglers by contesting scuttles. The execution, however was very very poor. By concentrating the exp in one place, it created a - there is no better word, I'm sorry - clusterfuck meta where everyone jumped in one place to contest it. Which is why it had to be partially reverted, to the point where the changes no longer serve their purpose.

The solution, in my opinion, is very simple - nerf or remove tooth and nail (and balance camps accordingly). This would give laners ability to slow down a good jungler - or abuse a bad one - the way junglers can do to them. Right now punishing junglers by stealing camps like in the old days is not a viable strategy until well into midgame, because laners suffer greater damage while fighting camps and also get less reward.

Scuttle patch could be mostly reverted after that.

This won't have the same problem as scuttle patch, because exp distributed around map will prevent excessive fights over it. It would, however, give laners a way to deal with or use skill difference in the jungle like junglers can deal with or use skill difference in lanes.

Thanks for attention
