The BG match-ups

Baraa

I really want to understand how the match up works besides the current rank of curse??. Is it random or based on what?. I don't wanna complain about it but it's really hard to win because of the "legends" I play against, maybe I'm not skillful enough or my roster isn't that good but at least match me up against even players. I almost win once or twice for every 10 matches and it's really Frustrating and it makes me want to improve my roster but it won't matter anyway because of the very high players I face.

Once you get to plat 2, it is 100% random with whoever else is looking for a match at that point.
