I watched the bot run more. I noticed that it kills the boss maybe half the time. I see you have a skill casting order before aggroing the boss. Skill 7, then 8, then 1, then 2, then you aggro. Can you make it so it is Skill 7, then 8, then 1, then 2, then skill 3? Skill 3 would increase the number of boss kills since the extra armor would make you live longer. The other idea was mentioned in previous posts is Ether feast instead of aura of restoration to balance out Rekoff's spike.
