Best beginner champion?

What is the best champion for a completly new beginner like me?

I think best champion for begginer is a tank like malphite or rammus, they can do it ok in any position and they are very good in late game even if your early was not very good

Rammus is a pretty good start for a new player. His kit is quite simple and pretty attractive for new players.

Choose whoever you like and learn him. There's a learning curve for every champion. For some its easier for others its harder. Its your choice. You are gonna have to spend at least a few hundred hours to perfect whichever champion you choose

something tells me the water is in the paper coil and it's going to be a mess

It would depend on your role that you want to play but I would recommend Rammus, Yi or Warwick if you're starting in the jungle.

for me. its garen all you need to do is spin and ult. Hahahahahaha

Master Yi should be a good starter champion.
And when you master his kit, he is quite good once you get higher ranks.

Rammus is a pretty good start for a new player. His kit is quite simple and pretty attractive for new players.

I always found Tristana super easy to learn and use
