Players should be allowed to leave matches where they're being abused.
As I'm writing this, there is currently a now 4v5 match going on that I was previously a part of.
The enemy team is baiting for responses, clearly a troll comp with several TPs and a Fiddlesupport who's response to "you have a fun match too" is "Should I?" while their Malz spams "Trololol". Not the best sort of people to play against, but the Rengar seems cool. I gave him a hard leash and he was thankful. That's a good sign right?
I'm still learning Rumble, and this is my second time with him mind you. In the Teambuilder queue I even warn them, saying I might have a hard time. My last hitting is shit, and I get put up against a Zac who can basically poke for free and sustain almost indefinitely. I know Zac's kit pretty well, enough so that I still try to jungle with him on occasion, so I know that his blobs have to be contested when an enemy laner is near. I let him push up a bit and try to freeze the lane as best as I can. I'm not doing horribly, but I'm sorta last hitting okay, and once I get a few points in my Q I'm able to actually start harassing him better, taking chunks out of his life that he can't get back within the next few seconds. Zac pushes hard, I'm getting low, ask for help and my Rengar, near full health, just sits at wolves and does nothing. I manage to bait Zac back, he misses his knockup, turret takes him out and I'm able to kill his blobs before he resurrects.
First blood. Cool.
Little while later, after once whiffing my ult, I manage to get a second kill. Cool.
Fast forwards about fifteen minutes and Xin Xiao has been camping my lane, our Fizz is roaming without having gotten his own turret and getting caught out, their Fiddle support picks up a double on my bot lane, all while Rengar is wandering around in the jungle. At one point after Xin has gotten Zac a kill on me he goes top and takes Zac out, but instead of getting rid of his blobs he starts farming minions, realizes the blobs are there, tries to smite one and misses it, feeds Zac a double.
Now I'm a jungle main, so I know missing smite on an objective, while bad, isn't a sign that you're shit. Just means you mistimed. But he completely missed smite on a slow moving blob that doesn't have to be secured with a timely press of the F key, just blown to pieces ASAP. Keep in mind here, Rengar's build thus far was a Skirmisher's Saber, he hasn't build Devourers or any enchantment at all, Berserker's Greaves, and he has a Triforce. Only time he'll show up in lane is to mop up.
At this point with Fizz never in his own late their Malz is breathing down my neck as well. I start feeding, hard. I can't get any CS to try and build any defensive items. I'm stuck trying to hold my lane while I have a Xin spear up my ass and Zac pouring himself into my lungs, and at one point there's a teamfight going on in the mid lane. We have a moment of vision along the river where I see two more enemies on their way down to the 3v3 happening.
I start heading down there hoping I can help. Even if I'm behind, landing a teamwide ult can help my team turn the tides, right?
Only while that teamfight was going on, the two enemies who blipped on the map hadn't gone down to mid. They'd stayed in river and jumped all over me the second I was just past the Baron pit.
Our Kalista immediately gets on my case for being caught out, and when I point out that I was trying to help with the teamfight she goes off on me for just being a feeder. I tell her that next time I won't bother coming down to try and help, and I'll just stay top, which is pushed back to the second turret (Rengar was getting Gromp at almost full health while Zac, at about a third health after killing me, took the first one by the way). Take a few steps out into my top lane to try and get some farm, and Malzahar rushes, suppresses, and I die.
I lost it. Unable to move past my turret, unable to help in teamfights, unable to get even one measly creep without giving up a kill. With Rengar building like a twat, not listening to cries for help or even communicating. Kalista is on my case, Rengar is saying I'm bitching at him when all I was doing was telling him he might want to smite Zac's passive a bit sooner before he's already reforming and asking him what his focus is with that build. Kalista is toxic, our Fizz is useless, and Leona's trying her best. At least Fizz and Leona weren't on my case, but the Fizz in particular wasn't being of much help. So from what I gathered, Leona was the only other decent person on the team.
The match has just ended, and I had to do that idiotic "type agree if you promise not to leave games again".
It wouldn't accept "I shouldn't have to play on a team with my own enemies." Go figure.
