Mindless gameplay should not be rewarded.
Right now with champs like
you can build
and rest damage and just charge the enemy team and do as much damage as possible without planning. With all the anti burst tools like
you can get rid of your weakness of burst damage, allowing you to deal massive dps while healing based on damage done. They take tons of cc and damage to kill them, far more than what should be required to deal with squishy carries. A normal adc has to strategically position next to their support to maximize safety while dealing damage.

"Oh wow- my carry is kind of getting hurt. Better E." or when somebody jumps on her ADC: "Ope- better use my ultimate now." the playstyle that this champion has is literally just be carried - you don't do anything else besides shield and ult in the same scenario as possible. This describes mindless champion = Tryndamere/Aatrox.
who can waveclear with ease while stalling for time in a 4v5 scenario.
like, do you know why this dude isn't allowed to be strong or buffed? The dudes broken as all hell.
