Board Game Arena

when on the simple game screen you see the button for arena pop up. going to arena mode you seach for opponents. i have noticed that it can take a very long time to generate a game even though the button pop up clearly showed someone was available. my wonder is why does the competition in arena care about preferences regarding matchups matter? i think arena matches should be made regardless of preferences and matchups will gererate much faster as a result. if you choose competition you get what you get. we should not be allowed to cancel a match from starting. if you cannot play then do not go into the arena.
