If the spreadsheet says it's correct, there is an extremely high chance it is. If you really, really doubt it, privately contact the author about it instead of cluttering up a thread.
What's the earliest point that a MM Hunter can spec out of imp arcane shot, spec into imp steady shot and then drop arcane shot from the rotation. I was under the impression you'd at least need to be Arp softcapped with a runestone, but just changing those talents and altering the shot rotation it seems I get a slight dps boost even with my current gear/gemming. At least according to Zeherah's Hunter DPS Analyzer
Does that seem about right? Would be kinda nice to drop to an easier rotation that uses less mana if possible.
