Getting out of melee range as marksmen
Against a handful of melee based champs (especially ones with lots of mobility/ms, and more of those thingsby late game), as a ranged/marksmen, it just seems impossible at times to properly escape their rangee (besides flash) without sacrificing damage/kiting. In split second moments it's not clear if you can barely get off by efficiently getting distance between you and them, (And maybe go towards a certain safer spot, like behind team/tower), or if you should go all out and fight back in the moment, possibly escaping yet barely, and them ending up dead. Other times it just seems both options aren't going to work and you just really can't do anything as a squishy with how sticky and bursty some melee bruisers/mages can be.
