I agree with JARS, every battle can be won. With my main character, i spent less than a couple hours doing nothing but arena fighting, until my end record was 50-0(wins vs losses, not kills vs deaths). I like how some battles are stacked against you, as it forces you to learn how to compensate quickly, or die. But likewise, it is just as likely to be stacked in your favor as it is theirs. Every single arena battle is winnable, no exceptions. That's one thing i love about this game, it's not like a normal rpg where if you're lvl 10 against a lvl 20, you have absolutely zero chance of winning. Oh, and it is possible with a high athletics to dodge arrows. I stood about 20 feet away from an enemy archer (yes, it was one of those uber arena hero champions) and dodged until he was out of arrows without taking a hit. You just sidestep one direction, wait until he's about to fire, then change directions the instant he lets that arrow go and it will miss every single time. Now sure, there's going to be that random arrow headshot 1hit kill of doom that you get...but its rare. However, i still say you should be able to pick up weapons off of the dead.
