I have put a lot of games in this season and as a player who has played every season of league i have to agree that games feel 1 of 2 ways.
A: You crush the other team to the point that they give up at 15 min or someone rage quits and they give up at 15 min
or
B: You get crushed so hard your whole team wants to give up at 15 mins or someone on your team rage quits and you have to give up at 15 mins.
I remember in every other season games were competitive and you would fight and claw your way through good games back and forth back and forth.
Riot has for sure made games end more quickly, which isnt a bad thing but this coupled with surrender at 15, the gold advantage from first tower the tower pushing advantage from Rift and most players being very sketchy in the early game leads to one team getting a huge 5-10k gold lead early and the average team simply cant come back from that.
