endless Arena combat !!!

i am in the game since 08:30 am in this Arena fight and it is currently 02:39 pm, 6 HOIURS!!!!...Dryax level 5 and the Imperial droid are still going at it, Dryax goes down from 1 to 3 points at a time while he is regenerating so at some point the Droid will kill Dryax but it will probably take a day or two maybe...the thing is i can't complete de daily either cause if i get out of the combat it doesn't count towards completing it. So this is kinda broken if you ask me here...i just don't understand how i can make 75.000 points of damage within a minute or two and then fall to resist a majority of the hit or get to inflict only 1 to 3 points of damage...this needs to be fixed. i'm on PC.

P.S. i have a video but it won't upload into the attachment for some reason.
