There are a lot of variables to consider when doing the math, some easier to setup than others.
Things we know will effect our damage:
>toughness (-1 damage for every 5 the target has)
>Spirit/Corp Resistance (which appear to be very close to 1% mitigation for every 10 up to softcap. Clarification would be nice if anyone knows)
>Disrupt/Block (each point would be -1% damage, and again how these are calculate additively or multiplictively matters and I'm not sure myself)
>initiative (chance to be crit, every 1% is a 1.5% increase in damage at 100 dark magic)
As far as calculating damage for direct damage skills that is easy.
Base Damage + Coefficient which is(( Scaling Statistic / 5 ) * Casting Time ) / Scaling Statistic)
So if gloomburst had a base damage of 100, and you had 100 int... you would find the coefficient for that skill((100 / 5)*1)/100) = .25... which means 25% of your int is the added damage in this case 25. So 125 damage.
Not sure how its calculated for Damage over Time... or if its even different
When calculating for dark magic and crit in general we can make it easy by just assuming we will always be at 100 dark magic (+35% chance to crit and 250% crit base) meaning that for every 1% crit we have we can add 1.5% increased damage to our abilities that can crit.
So going back to our gloomburst example 125*1.75 = 219, so if we only had the crit chance from dark magic that would be our average damage against a target with 0% chance to be crit. Unfortunately that is not the case in game and we need to calculate with out targets chance to be crit on top of our bonuses from passives and gear. But this shouldnt be too big an obstacle.
Should we use different rotations in certain situations or against certain archetypes/class? Maybe there is a fast burn rotation that can be used against weaker targets that you know wont be getting any kind of healing or guard, and you know detaunt is unlikely as well as a cleanse. How should we deal a guarded target/detaunted etc... if we have to attack them.
I'll end here for now and do a bit of my own math below on what I would consider the average type of target I will run into, and try to come up with the fastest burn for them. Going to need a lot help here, if anyone can look it over and see if I'm forgetting any variables or setting it up wrong. There are of course a lot of variables I am leaving out for the sake of seeing if the math I am setting up is correct, just making it easier. Things like cleanse, etc... which you would obviously change up for say a BW.
Remember this is just an example, for the sake of checking math/formulas etc... Though if you want to post your rotation if it's higher please do. That's the whole point of the thread. Or if you want to argue the way I am setting it up is wrong or is taking too many things for granted.
Target:
>200 toughness
>300 spirit/corp res
>10 disrupt
>4000 health
>150 ini (16% chance to be crit)
Me:
>580 Int
>1% chance to crit
Tactics: Endless knowledge (already calculated) and Shadow of Distaster (-255 spirit res while chillwind is applied to target)
0 seconds - Cast WoP
1.4 seconds - Cast CW
2.8 seconds - Cast GB
3.8 seconds - GB hits 470 dmg
Spoiler:
4.4 seconds - CW tick 1 hits 166dmg
5.8 seconds - HoR tick 2 hits 607dmg
7.4 seconds - CW tick 2 hits 166 dmg
7.8 seconds - HoR tick 3 hits 607 dmg
9.8 seconds - HoR tick 4 hits 607 dmg
9.8 seconds - Cast GB
10 seconds - WoP hits 697 dmg
10.4 seconds - CW tick 3 hits 166 dmg
10.8 seconds - GB hits 348 dmg (no SoD debuff from CW) alternatively you could cast IW at 9.8 seconds for 319 damage instantly if they are in range, dealing 1789 damage on average in less than 1 sec. This assumes perfect latency and cast times.
Frozen touch: against the target will deal 53 damage, unless proc have some kind of weird formula for damage calculation. In the rotation we have 7? (WoP is direct damage?) (7*53)/4 for 93 damage, and disrupt? 84 damage.
at 10.8 seconds the target I made up above will have on average taken 4525 damage, and for those that run the WoP tactic they will have done 4118 damage on average.
I'm going to stop here for today, because I don't want to progress or spend any more time If I am overlooking something huge or doing something terribly wrong. Hopefully you guys can help me out.
