I have some ideas to make yasuo less opressive

These are just some ideas to make yasuo less frustrating to play against. Please give me your opinion. Remove his flow shield from his passive and move it to a new passive in his W, for every projectile yasuo blocks with his WindWall he gets a shield [the shield would be fat( I´m talking realy fat 300-1000 of non decaying shield for 10 seconds depending on what you block)] the shield would also proc when he ults but only for 150-500 depending on rank. The shield will be bigger if the projectile is an ult and if it absorbs more than 1 projectile. Now that you dont have the shield meter give him mana. Infinite dashes are frustrating to play agaisnt so give his ablities a low mana cost for example cost 30 for Q and 10 or 15 for every dash (but every third dash yasuo does wont cost mana)(maybe also increase the dmg of his abilities slightly) , and 60 for windwall( he would have good base and scaling mana). This will make his dashes not infinite but close to it. I think this could remove the I´ve got a shield every 7 seconds if I just walk around aspect from yassuo. Please tell me what you think. Im not a game designer this might be ( and probably is) shit.
