Rank distribution is not accurate

Hello,
I am a platinum 2 ranked player, but for some reason I have masters, & predators in my ranked lobbies?
How is this possible?

I thought ranked only allowed for 1 rank division above at most to be placed in a lobby with you.
Meaning I should either have golds or diamonds in my lobbies?
This makes the experience absolutely horrible for casual players.

I understand queue times may be longer for higher level players. If they don't want to wait for people to join the queue at their rank. Make them go play unranked.
Lower level ranked players should not be thrown in the lobbies with 2+ ranks above them.

It's an absolute slaughter & on top of this the -RP lost is ridiculous.
If you don't change the way the rank queue works, at least make it so people 2+ ranks below players don't lose RP. (For instance, Platinum players shouldn't lose RP, if there are master or Predator players in their lobbies.) If this isn't possible, then it must be possible to make it so if a Platinum player is killed by master or predator they don't lose RP at minimum. 

Thank you!
