Hey guys, would be great if some of you could give me a feedback on which champions I should focus on.

 This is how it looks like right now. 

Ideally a screenshot of champions that you have would be useful. 

Generally, if you go to the champion selection window you will find there on the left a small recommendations button. Click on it. You can trust the score in 80% of cases. Focus on those heroes with higher scores.
