What if the shared exp in botlane gets increased to 70% exp instead of 65.2%?

Hello all ^^

I'm wondering if the exp gain with two champs is increased to 70-75% instead of 65.2% will that make botlane feel better? Atm you will automaticly fall 1.5-2 levels behind before midgame begins (not calculating jungle mobs, kills, assist, deaths or any other exp increases except minions). Levels make so much diffrence (especially toplaners know this (the lv 6 vs lv 8 after 1 mistake matchup is the best example)) With all the recent drama about botlane. I think this is a good solution to make botlane feel stronger. Instead of buffing/nerfing values all around, botlane will just get more base stats and its automaticly a buff for all botlane champs. Also botlane could get so much more then safe farming range + support combo if you dont fall behind on exp. Last why is it 65.2% exp gain with two champs, what is the logic behind that number ? Is it intented so you will fall 2 levels down in mid-game ? If so it's weird. You want supports and adc to feel impactful but the core design of shared EXP makes them weaker mid-game/late-game where i thought adc and supports where supposed to shine?!

Let me think what you think in the comments, i'm curious to your opinions!
