Game has become very noob friendly

I disagree, the players in this game have never been better at it. Seriously, what passed for pro back then is what the average gold player is at now skill level wise. Every adc main knows how to orb walk, every jungle main knows timers and paths, every mid main knows when to roam, every top lane knows when they can win a fight, and every support knows where to ward and who to protect.

Do you want the game to continue??? Then whats the problem?

I'd love to know why you think that. Stating an opinion without any reasons to back up your opinion doesn't really offer much for a discussion, only speculation on our part as to what you are talking about.

I think it isn't because nothing is taught to people who play the game. Everything is learned from playing the game a ton or watching youtube videos or such. No one who just picks up League as their first Moba will know what to do like a Challenger player will. They might be able to move their character around and use abilities, but they don't know when to use them, how to use the effectively, how to use them in multiple ways, what items to build, when to deviate from your normal build, when to go aggressive, etc.

As a noob fresh to summoner's rift, I disagree. There's no in game tutorial that teaches you that the job of a Jungler or a support is different than the other laners, but you're still expected to magically know that when you get into matches. I don't think there's a single other game I've played where a support's job is to literally stand there and not attack unless the enemy hero comes into range, and even then killing the other hero is strictly forbidden most of the time.

Also, there's no tutorial on items or what those item stats mean. When I first started playing, I bought nothing until I had a little over 2000 gold because item build paths are never explained and I thought that buying a lower tier item meant I was just wasting gold I could be spending on something higher tier . It wasn't until my 5th bot match that someone noticed my weird itemization, sat me down after the match, and explained to me how item build paths worked, that I realized I'd been doing it wrong.

I'm not even high enough level for runes yet, but the idea of doing a basic math course for every single one of my heroes to get the most out of their stats doesn't sound like fun.

I think it took me till level 15 to actually realize you need to kill minions to get gold. Then I never knew dfg had an active till they removed it. It is difficult for a new player to actually figure out what is going on. Along with trying to figure out what all the champions can do
