Hey, if you like me, I've found myself in the GA way overmatched. I usually look the opponents inventory to see where they are and if I have a chance. The answer is usually no, myself, I'm rated in the Arena around 235 to 300k. Ok but terrible, 91 in the Fleet arena. But this player I'm up against is number 7 in the Arena and 4th in fleet arena.
Check out the screenshot, think I'm overmatched?
