Arena problems

while playing in arena ive experinced some toons . waiting my toon to attack my opponent . they even dont dome , they just attack in one place. is that bug or what?
and HOW do DEALER PERK WORKS ? need ADVICE NEWBIE HERE THANKS KODOS TO MODS

This is because they have been set too avoid enemy 50 yards this causes characters to just sit there and not move for some reason and dealer multiplies the value of an item by 10* when selling it :smile:
