simple explanation being speed increase= shot rotation loss.
While it seems nice to have your speed increased the ability to weave in other shots provides much larger dps increases to the uncontrollable at.sp procs. Hunters used to believe the T2.5 bonus on reduced rapid fire combined with rapid killing was the key to max dps. that all changed with hunters role being based around shot roation by blizz. The most humerous thing being they decided to make a class timing dependent with little or no regard given to server/client latency.
Knowing your shots is the key to higher dps. combined with a BM spec lol
Serpent Sting: 44 DPS 2.4 DPM
Arcane Shot: 382 DPS 2.49 DPM
Steady Shot: 411 DPS 5.60 DPM
The ideal shot rotation would probably look something like the above picture over time you would shoot things in the following order.
Steady / Arcane / Auto / Steady / Kill Command (if available) / Auto Steady / Multi (if no Crowd Control)
[repeat]
Although aimed shot does a good amount of damage, it resets the Auto Shot timer.
And Mord is right on on Aimed shot.
In the time you are casting ONE Aimed Shot you could have cast
1. Auto Shot
2. Steady Shot
3. Arcane Shot
And you’d be most of the way through casting another Steady and Auto Shot
Essentially, shooting *ONE* aimed shot costs about the same as shooting almost *FIVE* other shots .. though it only does the damage of about 2. It does however retain its value for when you are initiating combat with a misdirect or whatever people to with it in PVP.
At the end of it all, Shot Rotation comes down to 2 things
#1 – Choosing the Most valuable shot you currently have available
#2 – Minimizing time spent not ‘casting’
If you’ve got a slow attack speed – you will have enough time to safely fit a Second Special into every second or third set of shots… that is less efficient in terms of mana consumption but does a lot of damage sooner.
