Don't know who to main in solo/duo
After playing a bit as adc I want to start main toplane. I love playing typical tank champions like 
and a little bruiser champs 
and 
. And my problem is that I love playing them but I don't know on which champion/s focus to play ranked. I'm afraid if I will play all these champions, I will not be good enough on either of them. So the question is, what number of mains is compatible to play in ranked games and git gud with them?
mid and vlad
mid and top.
and am decent on 
and 
. While Kha'Zix and Rengar always do the same thing but Udyr has lots of versatility when it comes to builds even if gameplay-wise he is extremely linear.
