Help with champion pool for climbing the ladder!
So I am trying to refine my champion pool a little more and I wanted to hear other's opinions, particularly higher rated players who know how to easily climb.
Right now my strategy is to tell my team that I prefer Top Mid or ADC. If I get top I play Riven (My Favorite Champion), if I get mid I play Orianna, and if I ADC I play Jinx. I have above 50% win rate with all of those champions on my account and they are champions that I enjoy. In theory, reducing my limiting factors in ranked, if I continue to play those champions I should eventually climb. I should mention that I do have back up champions for Top, Mid, and ADC and I also have champions picked out for Jungle and Support just in case. It is not an issue of only being able to play one champion.
I've just recently made it to around Gold 3-Gold 4 and I feel like I've hit a wall. My question is, should I start to focus on one lane and the small pool of champions I have there or continue to develop my 3 preferred lanes equally? I would simply main Mid lane because I feel like I have more influence over the outcome of the game from there, however my favorite champion is Riven and she plays top lane and I have a personal goal of using her a decent amount on my journey to higher elo. So I'm kind of stuck there too! I could shrink down to just top and mid, but then I still feel like I am somewhat limiting myself by not focusing on a single lane.
Any helpful advice is appreciated!
