As I moved up in rank, the battles have grown in length. I could knock out 10 battles in 30 minutes when I was a lvl 5 to 10 guy. Now, it takes at least 3 times as long for a battle to end. I should've fought more at lower levels. Even considering not leveling anymore so I get more arena tickets more quickly. I know once I move up the ranks, it will take that much longer to find an opponent and add on to that the length of the battle.
I can't even IMAGINE how long some of the multiple PVP battles must last. They should get 4 times the tickets for 4v4 PVP, 3 times for 3v3 PVP, 2 times for 2v2.
Just an idea.
