Rito why you do this to me

Went 7-3 in my promos and got bronze 4... Didn't even have bad mmr or anything, just got dicked over. But it didn't just happen to me, everyone I talked to dropped ranks after going positive in their promos and some of my friends were even in plat and they got placed in silver 1 and 2. So now that means people in silver are going to be playing with Plat and Gold players... Thanks for wasting my time Rito I could have just gone 0-10 and gotten the same rank, whats the point in even trying?
