I'd still be a little wary, given how haste affects shadowmoune and its proc (depending if you're using the /cancelaura or not)
Aye, the SM proc and 2t10 will most likely alter those breakpoints slightly, but it would be impossible to accurately estimate them with in-game testing. I'm wondering if it's possible to re-add them both to Simcraft somehow? I mean, they must have been coded for it during WotLK.
