I am not really talking about precasting here (if you're really into that, why not precast sflare > swiftcast > tri-disaster rotation?). I assume you know your high level play and am not going to make judgements on that XD Merely that your motivations are incorrect and your math is not solid.
I'm simply talking about the matter of prorating dots and why it makes sense mathematically.
Sure we can define the fight start at some given point, and shorten the dots there. These are two separate arguments though, you're talking about chances of catching a tick and I'm talking about how you can remove all randomness. You questioned my math and my precasting - I'm saying the former is rock solid, the latter we can certainly look at it your way and see if it is correct.
I don't necessarily disagree with your conclusion, only your motivations - thinks like unlucky and very likely imo have no place in models.
Anyway if we assume precasting and lets just say you get off Bio II at 0.5 seconds after pull, then it looks like this:
[0.5] - Bio II
[3.0] - Miasma
[3.5] - Bio
[5.5-6] - Swiftcast Sflare
We'll prorate everything to 6.5 sec cause thats how long it takes for the second ruin to pop out. Yes I know sflare has 0 chance of applying, so we will take that out of consideration for now.
Total damage is (6/3*35)[Bio II] + (3.5/3*35+20)[Miasma] + (3/3*40)[Bio] = 170.83
So if we assume precasting for tri-disaster it will look something like this. Bear in mind I am guessing at delays here, but I think they are reasonable.
[0.5] - Sflare
[1.5] - Swiftcast + Tri disaster
[4] - Ruin II
[6.5] - Ruin II
So for this we have (5/3*110)[DoTs] + (2*80)[Ruin II] + (2*25)[Sflare] = 393.3 + Tri-disaster upfront damage
So the difference is only 222.5 potency.
Tri-disaster would have to hit for 80+ potency to make it worthwhile. Unsure also if it will apply miasma direct damage, but it makes sense for it to not - because it will have its own potency, and applying auras is not contingent on direct damage.
It is interesting to note that this only results in slightly higher damage than simply precasting tri-disaster (or swiftcasting it). But it -does- result in higher damage, so its worthwhile if you know tank positioning. If you also know the positioning AND its not on the boss's current position, you could precast sflare for both cases and its pretty good.
Also to answer Judge's question about why not only prorate the first tick...well yes, that is essentially exactly what its doing.
Any tick that is equivalent to floor(duration/3) will basically mean a guaranteed tick. For example, prorating Bio II to 5 seconds results in 1 + 2/3 ticks...this is equivalent to only prorating the fractional tick and adding in the guaranteed one.
I think it will make sense once I get my simulator working, and we can see the differences in openers.
