Short post! Since the "changes" to match-making, it's been pretty hit-or-miss. This goes for solo/duo queue primarily. Either all of the players on my team are very skilled and we stomp the enemy team, OR the enemy team significantly out-skill my team, and my friend and I literally have to teach people how to play the role they picked.
I've climbed almost +150 ELO these past several days, but now with some strange low FPS drop (started on Friday) and a hit-or-miss matching-making system, I'm afraid to play ranked anymore.
The enemy team notices "poor" players faster in a higher ELO and capitalize on it quickly, at least I know I do. I'm not particularly happy with the longer wait too, since the results do not seem warrant the wait if it is a one-sided match.
Occasionally, the teams are evenly matched. And I'm not upset at losing against a more coordinated team--in fact I like a challenge, however, it is not fun to face people much easier than you in ranked one match, only to get stomped hard the next match because your ADC insists on being the ADC and only farms all game, or the mid never buys a ward mid and gets ganked constantly and then gives up and blames jungler for not babysitting.
TL;DR: I've had severe headaches with the teammates I've been matched with these past few days that almost makes me want to uninstall, lol.
