There is no one definitive answer that fits all situations. The tradeoff for casting HM or not depends on several factors including:
1) Your spec. If you are MM with Marked for Death, you do not cast Hunter's Mark, instead you start with CS or AS to get the pseudo Hunter's Mark.
2) Your DPS on the target, which invloves the folloawing factors:
- What standard buffs you have and what debuffs will be on the target
- Your rotation used
- Whether you have dynamic buffs like RF, BL, trinket procs etc
3) if they are other hunters in the raid that benefit from the mark
For a given scenario, you can figure the value out in a sim for configuring the run per the scenario. Do two runs, one for your DPS with HM and one without HM.
Then find the time where the runs intersect in damage done when you start the DPS for the HM version 1 GCD late due to casting the HM.
Here is an example using my character as SV for a 1m (unfortunately FD cannot do shorter) run with using RF and with all buffs/debuffs immediately on the target (this assumes you can perform a perfect rotation like FD does):
DPS with HM: 47903 = a
DPS w/o HM: 45828 = b
Hence, the formula for the crossing point is:
b * t = a * (t - 1)
Thus,
b * t = a * t - a
(a - b) * t = a
t = a / (a - b)
So for this idealized case: t = 47903 / (47903 - 45828) = 23.09s
Hence, considering how small HM's AP is to our overall buffed AP, the decision to cast HM for you being the only hunter on the target is a lot longer than it was in previous expansions and vanilla. Assuming that your actual DPS scales the same for both cases with and without HM that the timing should still apply.
