Is riven a good champion to learn more and more about the game despite the skillcap

I heard this from exil who is a plat riven main who also plays yasuo (currently, you just need good macro for yasuo top and all you need to do is splitpush and let kills come to you). He's a smaller lol YouTuber with only 60k subscribers. From what I can see, you just need to practice the fast combo in the practice tool and go from there and learn the other 100 of them later. I actually used her a couple times and did good but I don't think I did the fast combo correctly but I managed not to feed or flame. What I did do is try my best to do them and I weaved autos between my Q's just like how ryze old ryze and the first ryze rework would do with the q between each spell although that's now the max dmg combo. I won both games and lol sumo says she's my signature champion since I won the 2 or 3 games I played her when really it's shyvana where I have over a 60% wr over 70 ranked games and the riven games were normals. I've actually been using attack move click on shyvana not help do full clears on shyvana which I can't normally do. If I actually practiced , I could probably be a god and a salty piece of shit and int people on my team if I don't like them or just flame them. That's every riven main and like yi, she's a greedy pick. You pick riven been to play her. Not because you need a riven on your team. Just ban malphite and you good. Keep in mind I never said she was easy. In fact, she's an even higher skill cap than ryze because of animation cancels. She's also quite rewarding. That's what I meant by become a god. You feel it. You get better micro as you go. It will help you with the game as a whole. Itcan also help you clear with champions who may not have the best clears without attack moving like Eve since she's squishy as fuck with no sustain (but I'm looking forward the the rework and being able to burst people down). For ADC, you will be alot better at orb walking. But she good to learn alot about the game.
