I had my guardian druid configured for 17yd swipes and thrashes but even when 15yds from a mob and able to hit it, those buttons were showing out-of-range (red). I've noticed this in Boomkin spec as well. Seems like it may be using default distances rather than current ones.

Interesting.... I'll have to look into why this could be. I believe the way we gauge in range/ out of range is via a built in funciton "IsInRange()" or something in that vein, so the work in calculating that is on blizzards end. I'll see what I can do though

Is this still an issue? I haven't noticed any bug here for quite some time, and I recently just rewrote most of this code

I haven't noticed this being an issue lately.
