Probably going to get downvoted for god knows what reason, but if you're a support main like myself and are at low diamond in solo queue, better get comfortable because you are going to be there for all eternity. In all the years I've played league, never has this game been filled with so many toxic, negative and skill-less people, at least in my games. In the majority of my games, there is always one guy who is doing badly in lane (usually top or mid) who wants to forfeit pre ten minutes because he died **once** in lane. If there isn't one of those, then there is someone who either picks a champion they can't play properly with, sometimes in a different position than it is meant to be played, or a guy who just can't play very well but is somehow diamond anyway (e.g. the one who keeps dying).
This has been going on for a while now, but never before has it been this regular and extreme. Plus, it doesn't seem to matter what I do in game, the enemy seems to always counter everything. You really do need more than one of your team to actually get ahead in this game now, but even then if you have the one guy who is behind then you've basically achieved nothing. You become even until a dice roll happens and one side wins. Also, don't dare overextend even for just a teemo-sized step because then their bot lane, jungler and midlaner will all pile on top of you. Instead, just position safely and sacrifice all the xp and farm until they inevitably have applied so much pressure to your turrets in multiple lanes and get even further ahead.
It gets worse too. I recently had a game where I played morgana support with a lucian and an eve jungle, and we somehow cant kill an alistar at level three/four who has no flash, after I walk up and give him a point blank Q. Somehow, evelynn didn't think to charm and chain our cc's together to secure the kill, and because she didn't alistar was able to flash (EDIT: as somebody pointed out, this may not has been a flash, but rather a w) onto a lucian at low health, kill him, and then proceed to escape through blue side tribush so that zyra bot lane can catch up and finish both me and evelynn off. And this is in DIAMOND. Mistakes are done here too, but it has never been this blatant and bad.
To make things worse, even when that game was obviously over, people don't want to surrender at 15 minutes into the game, the time it is acceptable to "give up". How about if you do well and haven't died yet with tons of assists? That means nothing if you die just **once** in mid game, and their team can get multiple turrets, drake or baron from that alone. And guess what? you will get blamed for it by the 0/100 person on your team.
It is so fun listening to chat and getting harassed almost every game, sometimes for no reason other than you don't follow the way that your teammate wants you to play the lane, even if it's wrong. You can't tell them it is wrong though otherwise be prepared for more verbal abuse, oh and also you better be there for every single one of your teammates all over the map at multiple places at once, otherwise they will ping you and wonder why you didn't come. How about full muting? Well that would be okay so long as everyone knew how to play decently, which is almost never.
The enemy team always seem to have it easier as far as winning goes too. If you want to win, be prepared to play from behind a lot and ride it out until your team catches up, and even when it does get to that point, be prepared to diceroll again over an elder dragon.
I am not asking for sympathy by the way, but I do ask that before you say "it's your fault you can't climb", reflect on your experience playing and ask yourself "Are my mistakes in game the ones that usually lose us the game?", and if that answer is yes, then i'm guessing that you're lower than diamond. There is probably stuff I missed off the "rant", but since I've typed a lot already I'll conclude now.
Anyway, until the state of the game changes, I'll be heavily reducing the amount of times I play, because it is simply not fun nor satisfying to win due to the reasons above. And if you disagree with that, then you are a very optimistic player indeed.
