Blackwell Fields in matchmaking

So hear I am again having to ask for someone to do something about the matchmaking. It keeps sending me to Blackwell Fields. Over and over I got on 45 mins ago started domination and I had to play Blackwell Fields like 3 times in a row. So then I go to firestorm got whooped so bad I didn't even try after thee game was so far gone. I jumped went on the roof and accepted the defeat since I was only one capturing points. So I'm all excited for a fresh game and what does it do? Yep you guessed it Blackwell Fields again. So for the love of all that's holy can nothing be done. I don't want my entire time playing the game to be the smallest most chaotic and stressful map in the whole game. At this point name the game Blackwell Fields, if you have to play it 5 times in 45 mins why have any other name on the mode be like domination Blackwell. If you custom search domination you will pretty much spend all your time at blackwell unless you take it off the search which I do but I shouldn't have too there 12 maps why does it always pull up Blackwell in the rotation instead of the other maps and I don't understand. I also don't understand why if I only want to play domination why I can't play at contaminated it's not even an option it's a fun domination map and it's shaded out so I can't even include it in the search.
