Season 8
The season where AD champions with CC get their powerspike at level 1 (if you're an ADC) or 3 (anything else) and never fall off because electrocute has such a stupid 50% bonus AD scaling:

I REMEMBER WHEN IT USED TO BE 30%,
Short to medium ranged ability or short to medium ranged auto attack champions are pretty fucked in this meta:

unless you're Teemo, Vladimir, or Malzahar, which can easily be dealt with either a
or a
, maybe Brand too
and practically all mages get their powerspike ONLY if they are long ranged:

I'm not going to talk about tanks, some are really stupid to play against like Sejuani, and there are also some which don't do a fucking thing to help the team, like Shen.
I literally can't play with my friends in normals anymore because every time I do the stupid match making places what's suppose to be my opponent gold mid laner in the bot lane with my bronze friends and the other team winds up winning because they're playing AD champions and I'm an AP champion main who doesn't get their powerspike UNTIL THE GAME IS ALREADY OVER. I thought the person who's the same elo as you on the other team is the one IN YOUR LANE, not the one getting 20 kills off my poor bronze friends I love playing with. And also because they're probably more experienced in the new rune system where the only thing I can take is in the Inspiration tree.
Don't believe me? Look at this:

If I play by myself, I win, if I play with other people, like 75% of the time we lose just because I'm in the group, it's not fun.
