Solo Queue MMR Problem

Hello, there are Problems with the MMR System in SoloQueue 3vs3 Arena, due to inactivity of the Bracket, People have to wait long time in Que as soon as they reach higher MMR, the problem now is, when a lower Rated Player get paired with higher Rated ones and he loses this Match, he loses same Amount of MMR as the Higher Rated Player in the Group, he only loses less personal Rating, which means, he will climb alot slower in MMR and so will his Rating, this is one of the Reasons why Solo Q is dead in my Eyes, what u Guys think about this? thank u

The Spectator NPC is also a Problem, People are allways able to see who is Queing where, above 2k MMR are very few Games which open, i can imagine that end of Season some will abuse the System, simply by Que with multiple chars of the same Class, lets say i have 2 Holy Paladins, both around 2.2k mmr, i could theoretically Queue both of them at the same Time in Solo Q and farm myself up? I mean due to the low activity alot i would not be suprised is some People did this already, what u think, how could this bracket become again more alive? i would like to hear ur suggestions on this topic, thank you
