Gaining and Losing LP.

Hey, I'm making this thread because I'm incredibly curious about how you guys balance LP gain/loss. I heard that the more games you win in a row the more LP you gain per game, which I could use some confirmation about. Which brings me to the entire reason I'm writing to this forum, If I win a game..Is it logical at all to gain 17 LP for winning a game, then lose 27LP for one game? I understand the whole 'if you're really trying to climb then you shouldn't have a problem grinding it out.' But It's incredibly hard for me to climb when on occasion, I get teammates who are so ignorant that they'll throw a game on purpose because they want to get some negative reaction out of someone for some laughs or whatever it is that gets them hard.

On another random note, I'm pretty confident that every promo game I've played this year, I've been matched up with a toxic jerk who likes to ruin the game for everyone else. Which brings me to another off topic but somewhat relevant question, when will Riot be implementing it's new Leavebuster/Toxic Player BANHAMMER system? I'd really like to know because I really like the ranked games where me and my ranked team get along and can have a laugh while playing, Unfortunately it only happens on occasion if I'm lucky. The rest of the time I get ignorant, selfish players who think the game revolves around them.

Thanks ! Currently
