Almost 3 years of playing, finally Riot has made me ragequit

I've played League since around a year after it came out. Hell i remember talon and skarner being released, but this season is particularly ass-backwards. After playing TEN placement games, i'm in at silver 4. Okay, much lower than i was but fine. Now with the new client BETA, I played the "one last" placement game they decided to throw in, and after losing it was demoted SIX TIERS(6) from SILVER 4 ~80lp to BRONZE 2. I just want to point out that Riot is worth hundreds of millions, and continually fucks game mechanics MORE AND MORE over time. Pathing? Terrible. Creepblock glitching you in place? All the fucking time. Now with ranked FLEX there can be silver/bronze team versus a plat/diamond team with 1 bronze; because that's Riot's logic. This has been a rant, mostly because I've finally uninstalled and will never be logging back on this game ever again. Riot, i've spent money with you guys, had said account banned for "leaverBuster" errors(i.e. servers crash/stop providing to my area without acknowledgement) and have never felt more dissappointed with this game as a whole. For all of your BULLSHIT and lack of CARE for your players, sincerely, FUCK YOU - Spector 911
