because certain champion classes they dont think this is power that needs to be limited to be fair to everyone else they just think dam assassins creed was cool what if talon could parkour like that across the rift.
another champion that is like this is tristanna one of the longest ranged dashes in the game on a basic spell too. but it gets reset for kills and takedowns. all because this long ranged champion that can run away or at people as they are attacking because ranged auto attack animations are cut short on the champion so that they can count the projectile flying time as part of it and they thought they can already run away and do damage at the same time what if when they got caught they could nope out of there and do it again with assist. it isnt balanced on katarina or kha zix and they have much less range and saftey but its balanced on some one one 3-6 times their range with an additional go away button too?
frankly most of the things they put in the game they only think if an adc or mage will complain about them being killed to fast or not being able to secure the kill. they never think what if melee? fighter and tank mains dont voice shit and while adc and mage mains cry about anything that makes their power fantasy of instant death from their skills harder.
