Damage Creep getting out of control...
... except when it comes to towers, those are useless stationary caster minions past minute 7.
ADC's have obscene damage and obliberate everything. To deal with that melee champions that are not dedicated supports and assassins need obscene damage too to keep up with that. However, assassins with obscene damage means you can't play a mage because, let's be honest, picking a mage into an assassin is like losing your lane on purpose, especially with the current itemization situation.
And what did Riot do against an oppressive champion class that towerdives with ease? They nerfed the turrets. Seriously, I have no problem with a Zed or a Fizz bursting me down when I carelessly walk out into the open with no wards. Then I probably deserve that. but when I already cling to my tower and struggle to even take some CS and still get oneshotted without any consequences... WHAT THE HELL DO YOU WANT ME TO DO RIOT? GOING AFK SO I FEED LESS?
And don't give me that "you have to protect the towers" bullcrap. Towers are supposed to be important defensive structures that should require an entire team to bring them down, even in lategame. Not some paper-mache filler with zero strategic value some random AD champ destroys while walking by.
