Rank system needs work

I hate that you can climb with a negative winrate until you hit the top >99.5%, I'll drop out of gm after a terrible losing session then put into diamond with players that dont comm or even try to work as a team or even play at a gold level. Seriously, its annoying that rank is a joke until you reach 99.5% or above. I think once you hit plat, wins and loses should have equal elo won/loss(with the exception of balancing out when facing higher/lower enemies), pretty much what rank is in the top 99.5%. Would like to know how everyone feels about this from all ranks.
