Don’t worry, Meepo is probably the hardest character, or atleast one of the hardest characters in Dota. Most other heroes are much easier. The game is still pretty hard, but because mechanical skill is less needed compared to game knowledge, it’s not much harder than League (still even League is quite hard, but that’s the nature of mobas.)
You could get into Dota too, I did after they first mentioned the idea of Vanguard coming to League a couple of years ago (also was kinda getting bored of lol.) Sure it’s a very different and hard game, but after I started to understand it, I haven’t looked back.
