Riot, there's no proper balance behind this marksman update.
It does NOT help at all to balance roles for their respective lanes and matchups if the moment you walk into lane as Katarina you can be met with an enemy marksmen who deals five times your dps over ten seconds. It doesn't help that you deal minimal damage at levels one to seven because you're so reliant on items and resets to make yourself effective. That's not good champion design, that just creates huge player frustration.
versus
in mid lane should NOT be an auto win for Ezreal 100% of the time simply because his attacks and ultimate deal more damage than my entire kit can over 3 seconds. His E should not be able to do so much more than my E without a ward. His ultimate should not be able to deal as much damage as mine and more until I outscale him in the very late game while being a global.
It simply doesn't make sense. And I'm so frustrated because it doesn't. It does not make sense.
