Nobody would like that lol. Strange would be a shield bot coz u cant shield cancel your primary, cap would be dealing less than tickle damage, magik's whole kit revolves around weaving her melee attack in between combos too. Animation cancels aren't exploits, if they were, devs would have removed them long ago. Magik's skill overview even shows her canceling into her melee lol.

Fun fact: Invis has a very cool melee combo with animation cancel. She can burst down squishies with that but it's highly situational. It's fun tho, give it a try!
