I feel like one of you is punching the other right now. Oo

There is always one zealot flaming any suggestion for changes, becouse " it is perfect as it is".
Its almost explaining why people were burning eachother for saying anything against the church in the past.Even if it was saying that earth isnt flat, or using herbs that church haven't acknowledged to heal.

Same attitude killed thousands of people.
Big brother is saying something is good so they feel safe to just go with the flow and hurt someone from behind of big bro's back.
At least in game noone is being hurt by others ignorance , resistance to innovationand simple ill-will.

I've made you look like a complete moron every time you post anything that resembles an opinion. And now you are suggesting it's because I don't like change. Can't you just admit that you are ****ing garbage at the game?

You dont even know my Eu accounts name, not to mention seing even one of my games, but you state opinion aobut how i play.
None of your opinions might have any value at all, if you talk about things you have absolute no knowledge about.
You proved yourself how ignorant, and agresive you are, all you care about is being negative towards someone .

Show a replay. You talk about a broken system and you are good but there are too many non winnable games. Here's the thing. I've gone over at least 150 replays for other players(not even my own games) I can safely say under 10 of them I actually felt were unwinnable. I've challenged tons of players to actually show me all the impossible games. At most they send 2 games, both where they are winnable(usually 1 is a 4v5).

So I've sat here reviewed games and can easily say you has no idea what you are doing at this game. Why don't you show some replays of your awesome skills.

EU replays work for me too

You completely missed the point.
Point is it shouldnt be win/ loss evaluated but individual players input in those games, as its not a TEAm ranked but solo.
No matter what would be the way to assign elo gain/loss people would always get to a point when they loose 50% of games.
Thing is if their elo changes would depend on their own actions it would feel much better, and less frustrating in those instances when they do good, but others **** it up.
Obviously there would be also games where its them doing bad and they'd loose more than now.But it feel more justified and undeniable.

ITs not so damn hard to put in any kind of distinction betwen individual players in each game, only reason to not to is riot laziness in this regard.
Putting such system would NOT change individual players placement in ranking,as it would affect all the others same way, but it would make it FEEL better and more justified.

This is where your lack of understanding of game theory really shows.

ANY SYSTEM that awards elo for actions that are not winning or losing, Creates sub optimal play. This isn't an opinion. This is simply how game theory works. If you decide "doing this action awards x points" even if it's just 1 point. Players will go for that action instead of doing the action that is more likely to net the team a win.

At this point your next post would be to suggest that we just associate a point value to every action that contributes towards winning. Ill save you a post and reply to this.
This thought process comes from a low level of understanding of league of legends. Its simply impossible to account for all the intangible actions(such as positioning) that are absolutely essential to winning a game. However produce no tangible effect. Other than increasing your likelihood of winning.

system might simply allow players to give 1 bonus and 1 negative for players they think deserve it in relation to other participants in that game.Viola, you have individual evaluation of performance that is not impacting the game itself.
Furthermore it would encourage players to keep trying even when other lanes are failing.Big problem in solo q is people giving up too fast and just not trying anymore, becouse no matter what they do they wil lloose/ gain same amount.
Would there be bonus trading? sure.But everyone can trade only one.Players positively/ negatively affecting the game would still be assigned more points than those trading.
Duo queues could be simply stripped off this privilage.

As for 50% wining.Its fundamental of current elo system, that is even said by riot.
In fact it is fundamental for any elo system.Problem is its not designed for evaluating individual participants in team games.
You yourself said that player that should be in higher elo win more than 50% games, which implies if they are right elo they win 50% games.
He might have different result than 50% on his way to that elo.Or short term results.But long term outcome of games in right elo will always be 50%.

This condition would not change if you make any personalization in elo gain, But at least someone suiciding 15 times in 20 minutes would loose more than someone making less severe mistakes.

As for replay.You already stated your opinion haveing absolutely no knowledge about how i play, now you want to see gameplayes to just find anything that would make absolutely random statement feel valid.
Its forming a thesis and than looking for any facts that would make thesis seem plausible.
To make what you say anything but a trolls blabbering you'd have to at least preserve appearesences that you form a thesis from a facts ;P - too late for this.
