Really!?

Before I start with this review, Here is a little backstory that happened moments ago, So I clicked the "Battle" button and it said It was looking for a match, I waited for about 30 seconds and clicked "Cancel" but as I have known in the past it doesnt work, so i close the app and launch it immediately only to see Im in the middle of a match already and my left tower is gone and king tower has half health, Im think to myself "what is this!?" Im shocked by this point, why am I shocked you ask? Because I was in the 3700 range and really close to "Legendary Arena" but I guess $upercell said "Nope, no free to play allowed in Legendary Arena"
So here is my list of complaints with this game:
1.Remove the cancel button, it doesnt work and I dont want players who make the mistake I did lose a match because your servers are bad and cant put players in a match.
2.Do something about Hog Rider, Elite Barbs, and Royal Giant, these are overused and matchmaking is so boring because these cards make up so many players decks, its stupid.
