Right now this is like really terribly un-worked-out. However, I'm not a big theorycrafter and don't have the willpower in me at this hour to sift through many pages of EJ to juggle my options with this addon.
Hands Warrior is a live "flow chart" of sorts for Arms Warriors. I needed a change from Fury, but kept cheesing up my Arms rotation. It's something you need to get a feel for, but even then, in a raid situation there's often quite a lot going on, and paying close attention to procs, buffs, debuffs and rage can be a bit of a pain.
Presently, the logic is as such:
Rend takes priority but don't refresh early
If we have SD, execute
If MS is off CD and >= 35 rage, MS
If we have TfB, overpower
If MS is off CD and low rage, save for MS
I'm open to suggestions. I spent about a half hour on dummies and found some nice feng shui with this setup, however, if your mathcraft is better (for example, my MS at >= 35 rage is an arbitrary number. This may not really be relevant in an infinite rage raid situation, but on dummies, I found myself rage starved on occasion, and couldn't use GCDs like a good warrior), I am definitely willing to change things up.
The addon lacks polish presently. The position resets itself every time you login, there's no way to hide it presently, the switches are abrupt and inelegant, and the window can't be scaled. Aside from the shine, it might be lacking a bit in "usability" - I can't make them clickable buttons, but just an icon and small text seems a bit bland.
I'm very much hoping for some suggestions for improvements, and will be actively updating this. :^)
