Ever since RIOT decided LCS was more important than their actual real game, the game has been like this. They nerfed turrets, encourage 3 tank team comps for level 2 turret dives, highly enforce a very strict meta that even more bans could not effect. So you see the same champs day in and day out.
You either super win, or super lose. There are no more counterplay's, no more coming back/come backs, if your team is losing in the beginning, you will lose in the end. Heck, it even used to be where 1 person could carry their whole team with good enough plays and skills and a little bit of luck and just the right champ, but now, PSHHH, good luck with that. IF your top lane dies 3 times, and bot lane twice in the first 15 minutes of the game, YOU ARE FUCKED. Unless your Vayne or Yi anyway, cause you know, BALANCED CHAMPS, Vayne 1vs5 penta , or Yi split push god.
Wins don't feel like a win when you can literally just roll your face on your keyboard and get a kill since your team composition is so superior.
Hell, if a tank made a mistake a few seasons ago, and engaged early, they would die, now if they fuck up, they still win! Thanks to EZ MODE champs like Naut and Ali. Lock on CC full team knock ups FTW!
Champs are also the same, Zed you used to have to LAND YOUR DAMN Q. Now, you just ult, ignite E, auto, thunderlords proc WIN. Doesn't matter if you even missed your Q. Same deal with talon, doesn't have to hit you with his ult blades, or the ones he throws out, literally just blinks to you autos you and you die.
I mean even supports do damage now, heck, even more damage than ADC's! Like ZYRA, i HATE this "support" champ. She is literally a mid lane mage just like Brand, and yet is the support to every single LCS game.
All of this is thanks to the LCS being more important. That 1% of players is way more important than the rest of us, because they bring Riot more money. Riot lost their way and became a corrupt business just like every other game company does. Money over game quality.
So yeah, ur not the only one feelin this way m8, wins just feel like mindless steam rolls, and losses just feel like horrible steam rolls that you know no matter how good you do, you just won't win in the end. And that's an awful feeling.
