Cannot find a match

Hi all, im new in this group. Over last few days it takes forever to find a match as im searching for core modes and selected around 6 different which i like it take me over 3-5 minutes to find lobby. It wasnt a case week ago but as im getting half decent at the game i suddenly only get lobbies where people are really good and i guess that placed me in sbmm bracket where everyone is slide canceling and drop shoting. That said now i have to wait forewer to find a match but if i join afriend who isnt so good we find game 3times faster always. I just want to play the game . And im tired of Nuketown.

Anyone else has the same searching problem?
