This game is way too easy sometimes

I started lol in early April and outside the first to matches Ive yet to find any really challenge from other player's thus far. Ive been getting friend requests from both teams every game and getting teamwork medals[despite the fact i never do teamwork and just kill every enemy player i see]. I thought maybe my low level account was the problem so my friend let me play on his pc for as many ranked matches until i lost i didn't end up losing any and got the most kills and assist in 5/7 ranked matches i played. I spent 2 years playing smite before coming to lol but it just doesnt feels as strategic or advanced as i imagined. As odd a fantasy as it is i want a moba I am not good at so i can work my way from the ground up learning everything and getting crushed in the process.
