Just spent some time on the test server, this is a significant improvement.
As a t6/t7 warrior using fully hate auged 101/20 donor and 79/20 haunted blade I was now able to pull establish aggro initially and pull it back away from my rogue bot on longer fights.
Now, as long as I waited to establish some aggro before sending my bot in things were completely manageable. It's not a complete pushover and utilizing flurry, taunt and equipping the necessary augs are key but aggro is much more on par with dealing with the aggro any player dps would cause.
Thanks again. This is a great fix.
