Best mage for solo ranking

Good evening everyone A new season is coming, do you disappointed with your current tier ? Don't worry !, This lady might be the answer....yep Luo Yi. i will explain why this underrated hero is good choice, the gameplay, and her counter heroes. First, we talk about her advantages. As a mage Luo yi has AoE crowd control skills but it's unique. You have to mark your target with yin or yang and mark another target with the opposite. When there is no another target you can selected, you can use the opposite mark of your 2nd skill to give crowd control effect to your enemy. you know what's next ? yep when your skill 1 hits the enemy's hero you will get shield and it can stacked !

She maybe is the best character in the game what do you think?
