GEEZ m8! Easy!
Not everyone could perform two hour arena session, it take to me, an average of about 3-4 minutes for a round (fight+potions+shop+inventory+characterskill)... in my best run i survive about 40 rounds (not remember exactly how much) ... so it's a lot of time and the fact that if my pc crashes, i have to so somewhere i have to start FROM round one it's frustrating.
I'd have liked saving/loading at a certain round of course ONLY if i survived until that. Just that.
Nobody want exploit a competition there, just, if you want a decent arena run you need lots of time, and, in m life it's limitating.
Be polite, it's not nobbing and not whining here.
