[Ask] Is this game worth it to keep playing?

I'm level 7 and was around 2100 trophies. I keep getting matched with level 8 or 9 players who have multiple legendaries or cards from higher arenas. I've now dropped back into the 1900 range and the game just doesn't seem worth it to keep playing. I'm not sure how I'm supposed to win these higher tiered games when I don't have the kinds of cards these other players do. What should I do?
