[Advice] Mid champions maining and climbing

Hello everyone, I started playing around a year ago in normal games and I have started ranked weeks before the end of S8 (Climbed gold quickly then stopped playing ranked). I don't really know what my level is (what rank I can achieve if I keep playing ranked) but I fear I do not have enough champion pool to climb farther than PLAT. I main Orianna and Vlad, I play in an average way every other champ (Anivia, Fizz, Annie, Ahri...). Should I practice another champ more in normal games? or spam Ori and Vlad in Ranked? When I watch midlane streamers that are good, they have a laaaarge champion pool and I keep wondering... Thanks for your time and advices! Regards, PhoW
