LoL used to be like a Sports game now it's like a Fighting game
With FIFA or NBA2k, which I used to beast on the former, knowing the sport and the players went a long way; just like knowing the champs and the macro of LoL was the key to getting good. Now with champs being able to do everything and there being a ton of damage it seems like whoever can press buttons the fastest is best. Where if you aren't amazing pressing keys quick then there is no reason to play. The player numbers seem to agree with me as sports games are played by everyone and are immensely popular like league was, and fighting games are still popular but very much a niche core audience as LoL is going now as numbers dwindle.
The best meta is where there are lots of ways to have fun. Like in sports there is perimeter shooting, post play, defense, offense, playmaking, passing, crosses, being a poacher or target man, covering passing angles, or using skill to beat people on the wings or break someones ankles 1v1. League used to be like that with covering, zoning, engaging, gatekeeping, sniping, seiging, safe routes, great ganks, harrass ganks, uber positioning and timing, objective control, win conditions, matchups, counters, etc. The game plays like most that stuff doesn't matter. The masses favor sports type games over fighting games.
p.s. Having a fighting game with a keyboard mouse is stupid as hell.
