Ranked Problems in General

If a red could answer this that would be great. I've been playing ranked for a while now and I've got three major issues with the structure as a whole. First, if there's any kind of logic behind the LP system, then it's skewed to force players to lose much more LP than they gain. The last 5 wins I had, I gained about 15-17 LP per game. In the last 5 losses that I just had, I lost 20-23 LP per game. If the losses could be capped at a static number like 15, it could possibly make up for being on losing streaks. As it stands now, it makes the climb impossible when you factor in the second point. Second, the match making system seems like it also favors players that are on winning streaks, by either lumping all the players that are on losing streaks onto the same team, or by allowing players to just not care and troll games away. Granted, trolling can be fixed if the tribunal actually starts giving out punishments again, but the problem remains. Third, and this is more towards a general gameplay aspect, is there any kind of work being done on changing how surrender works? I understand that waiting until 20 minutes and then needed 4/5 votes to surrender is okay in most cases, but in games where one team is at least 20 kills ahead by 20 minutes, and people just refuse to surrender, it causes me a whole lot of stress, knowing that I'll have to suffer indefinitely. Some suggestions include something like the surrender vote coming on earlier depending on how far ahead the enemy team is (the game can track tower, champion, and dragon kills, so possibly it could see just how much of a disadvantage the other team would be at) or perhaps lowering the pass requirements after a few failed surrender attempts and the team's at a general disadvantage. I know it might just seem like some lowly gripe from some stupid bronze who can't figure out how to carry himself over this, but I feel like there's no helping the people that want to climb out of the absolute dregs of solo queue but are held back by ruthless losses and scant gains. Anybody else have any thoughts about this? I almost don't want to play after the sheer amount of losses I just had today. It took me 19 games to get within my next highest promo and it took only 5 to put me terrifyingly close to falling back into my starting tier.
