Remember that most games nowadays are decided on which team gets first blood.
Snowballing is crazy in this game and it looks like it won't be toned down anytime soon. Any player on the enemy team that gets first blood has won the game for their team and should receive 4 honors. Any champion that gets first blood from a tank top to support can snowball out of control, because they get a boost of gold to get items or components faster than you. It means they have more pressure in lane, can push faster which ends up in the first blood tower taken to increase that gold lead and completely runaway with the match. Even if a priority champion took the first blood kill gold, assists also give a decent chunk of gold also and turrets give global gold. Why? I don't know.
Riot tried to tackle huge snowballing but failed. They decided to increase turret health for tier 1 turrets but minions now deal more damage to them. Champion passives work on turrets like Gangplank's passive, Akali's passive, Xin Zhao's passive etc but not Aatrox's W, why? Also red buff affects turrets which is ridiculous, red buff should only be for extra damage to champions whereas a mountain drake should affect turrets which it is designed to do. And if your playing a full tank that struggled to deal damage to turrets, don't worry cos Demolish exists. Yeah Demolish is kinda garbage, but it is still an option if needed.
So keep this in mind all you players. Until snowballing is reduced, you just need to pray that your team gets first blood and snowballs that lead. And don't think that your turrets will protect you when they are made of paper.
