This game is almost impossible to play and it's making me sad.

It takes ages to find a ranked opponent that's a similar rank to me, I want to play this game but at the same time I don't want to get stomped by a high ranked player that knows everything. I also have the matchmaking on arad continent and it doesn't seem to matter. It's either I wait forever to get into a game but my enemy cancels or I can't find one. Do I have to play in a specific time or something?
