2 Infernal Drakes (actual problem, but drake was before too that just gave more gold)
A 8+ kill advantage in bottom (player made problem, riot cant do much to fix this)
A 30+ CS lead in bottom (2 additional kills) (player made problem)
First Turret Gold (actual problem that i think should be removed, i agree)
A Midlaner who has their Morello complete which gives them literally everything a Mage wants for LESS THAN 2.5k (has always been like that)
An open mid from the midlaner and jungler trying to help bottom (player made problem)
An 8/2 Lee Sin/Hecarim/LeBlanc that can and will dive successfully time and time again (they're just op atm. lee and leblanc will probably recieve nerfs soon)
Tilted enemy(s) (player made problem)
A monopoly on both jungles (??wat??)
And possibly even Rift Herald (actual problem)
You see, most of these problems are player made and are basically caused of tilt; a thing riot can do very little about, but there is something i think you forgot that was in the 5.22 notes
Minions push faster depending what team has destroyed most towers in a lane. This basically automatically creates pressure and has very little to do with actual strategy in the game, and it is honestly just unfair to play against.
Drake: I dont see too much trouble here, all the drakes are useful in some way and can make you snowball. I think it was a fine addition
Rift Herald: Eh, i dont know what to think about it. :-/
