How Make this game less tilting

First of all I'm looking forward see your idea about this topic and I bring my own for the start After all its a game and meant to be enjoyable not tilting

Well I can address most tilt come from little mistake in lane and early game can cost u a lot until 10 min , 20 min or even end of game u make a mistake and it stick with u for long time and u stuck in game until it end well to solve that need make mistakes be less punishing In order do that we need address what is most punishing thing in early game and I think it's summoner spells cool-down Here is a scenario u make a mistake don't pay attention to jungler start as top laner he gank's u use flash to run now for next 5 min u are at huge disadvantage he gonna camp u must give up cs enemy laner gonna freeze and u cant do any thing about it unless u get help but most likely u wont get any in solo Q and by the time u recover from that mistake u lost a lot of xp and gold if u didn't die a lot after that

Solution: make summoner spells scale with (or only flash) lvl maybe at lvl 1 flash have 1 min cd and lvl 18 6 or 5 min cd it make game less punishing for a little mistake early and reduce jungler influence early game (I'm jungler main) and also make game less boring and fun ppl make flashy plays all around map in early I know some combos with flash are huge and by that change it wont matter that much in late game when flash have long cd its gonna be same

This change also benefit support and adcs because they get lower amount of xp they always have lower cd summoner spells U may also say "but we cant track enemy summoner spells and abuse it" and it is possible still but need more calculation u need know enemy lvl and know what cd flash have on that lvl
