Difference in champions starts to be a bit bigger than it should be
Years ago, of course there used to be champions that sucked more than others. You'd have to work twice as hard to make them work to get the same result as of playing a normal champion.
But right now, holy fuck, some champions are just over the top have super strong kits and they simply have more abilities and more stats. Easy as that. Super unforgiving champions. Meanwhile if you play garbage trash, at this moment of League, making a mistake is super unforgiving, and making them work is becoming harder and harder.
In short words: discrepancy/gap between champions is becoming way too big Let's hope they start with the fixes/mini-reworks. Also while we're at it, when are we going to nerf Irelia, Camille, Ornn, etc ?
