I'll look at the new AoE code but just to explain it shortly, it'll basically run AoE if there are any clusters around you that you are facing, not just if there's a cluster near your target. That means a lot more AoE.
Now there are hotkey features for this and gathering focus, if you enable them by accident, it'll certainly seem like the CR is broken, or as described earlier by DewdInTheNewd "All it seems to do is use focus CDs to build up as much focus as possible to spam arcane shots". Sounds like Focus Regen mode was on
Anyway, I'll look through the code to see if there are any obvious issues, I don't have a lot of time this weekend nor too much next weekend either and ill be gone 3 weeks after that, so don't expect any major updates for a good month or so
