I haven't really had a chance to do the math on this, but I do know that improved arcane shot changes the cooldown of aimed shots down to 5 seconds. Assuming a 5 second aimed shot, what would be the math to optimize around that type of shot cooldown?
At first, I didn't think this was the case either, but from my own testing, with a 5/34/12 spec, the arcane shot and aimed shot timers are linked. Either the improved arcane shot talent doesn't affect the cooldown, or we might see a shifting in talents. I know I don't have as much credit on these forums because of my non-existant post count, but I was wondering whether the math would already be out there to determine a good shot rotation?
shadowhand i can assure you that imp. arcane shot doesnt affects aimed shot cd. yes i also had that idea and tried that.
and no, aimed shot cd still is 6 seconds, it affects only arcane shot cd, making it 5 secs.
There was a time when Imp Arcane Shot effected Aimed shot but that was a long time ago. I found out a few patches ago that it was changed when I respecced back into it. What Starks said is how it works nowadays :)
