@Riot potential Aatrox buffs

Hi As someone who both mains and enjoys playing i understand how he works,and after tons of games with him,i can say he is High risk medium reward champion. This is the basicly first time i ever ask for Aatrox buffs myself and creating a thread for that. here some changes i though could help: AA range increased to 175 from 150,total with ultimate is 350 instead of 325,just a minor buff because you know the Living sword needs blood and its pretty big sword. Another big problem is Dark flight.Lets admit it,this ability sucks,The cooldown is high,the health cost is high,the damage is shit,the range is pretty fine,the cast time pretty fine. Currently this is his biggest problem,as his only mobility spell,the reward is low and the punishment is high. if he misses,congrats you just wasted 10% of your current health,and vulnerable without mobility,if he hits,congrats you still wasted 10% of your current health,did low damage and knockuped your target for 1 second,still very vulnerable. i dont think health refund neccecary,but i think you could reduce the cooldown by 2 seconds for each enemy hit,this could be some good reward :P I think his W is overall fine(max hp true dmg intensifies) his E kinda sucks but its got its uses. Another buff i can find is in his ult:MASSACRE i think i can find an identity here,not inspiring his allies,but actually massacaring his enemies,i think you can change the flat damage,and replace it with: Aatrox gains 5/7.5/10% of each champion hit as bonus health(calculated per each champion),while damaging each enemy heat by the same amout. Last idea,i think changing Aatrox's Blood well maximum amout to max HP scaling per level,as well as putting an attack speed cap. I support the idea of Health tank ,because he uses Health as a resource,Filling it with His passive,Gaining and Draining max health from enemies(by the Massacre change). I think this would give Aatrox a healthy Identity,as a Health Fighter, Full Middle of teamfight diver,who can actually change the tide. I would be REALLY happy if a @Rioter could share his opinions on my post

EDIT1:Another possible change,if Dark Flight is interputted,Half of the health cost and cooldown are refunded(kind of like zac)
