I'm good at overthinking!
My team build is pet based. I want to sic (HAH) one on aow, then another grab adds. With vanilla KA, chars focus on the highest level, then the most damaged. Adds are ignored. With my changes, adds are engaged by OTs if they start to clobber the group. The MA stays on named. The thing with aow as you know, is that dps needs to be controlled. Thus, while the rest of the team dispatches adds, the MA is still going to be going on aow. Etc.
What I envision is something that can respond appropriately. Yes it's automation, which I love. Anything like it out there? If not, then I know what my first Lua project will be.
