When will this change?

I don't post a lot of rant posts. But enough is enough. I am a support main, and obviously I have to rely on my teammates to carry the game. And there are some games that I will lose, which is a given. But at least riot should reward those players who play really well even though they lost. When we win a game, we recieve 15 LP but when we lose, we can lose up to 62 LP. WTF!!!! Not only that, we receive minimal IP on losing regardless if I am able to secure more kills than my adc or I feed like the Red Cross in Africa. And being a support, I don't have a lot of chance getting an S rating (I'm in bronze btw). So that reduces my chances of receiving more IP than my teammates even if I win. Riot should reward those players who play well even if they lose. And in ranked especially in bronze and silver everyone plays like as if it is a team death match. No one wards, a player is pushing when a team fight is going on and a player just does a suicidal cavalry charge into the enemy team. A lot of players do not know how to achieve the objective or don't even know their objective. And one of the most annoying fact is that, when a game is lost, they just won't surrender. Being a support, I know what my objectives are, keep my adc alive and help out my teammates when the towers start falling. And yes, I am not at all a good players. Else, I won't be in bronze. But this mentality has to change. Whenever I tell my teammates to ward, their answer is you are the support, you ward. Like WTF!!
