The biggest issue I have with your assumptions now comes, as it seems pretty contradicting to me: you assume that the ele is the only person stacking any might in the group. As an engineer stacks 6 might on average, using a somewhat close to optimal rotation (little vuln stacks lost, assuming no other party members do vulnerability, but small gain in personal damage) and two warriors using FGJ or Warbanner, of which both stack 3 might, just to maintain the required fury, this just becomes impossible. Especially considering the mesmer has to use the signet to get the last bit of fury uptime done. You can’t be the only person stacking might when you assume permanent vulnerability and fury.
As next point, which you didn’t nessecarily involve but follows from the topic “speed runs”, there is swiftness. Okay, no big deal, two warriors with warhorn and/or a guardian with Retreat easily take care of that. But at the same time, they again gain an additional blast finisher on a 20 seconds cooldown to blast your fire fields, resulting in 6 might. No need to use Mace offhand, since it only has a 1% damage increase over pure Axe when vuln is being capped (which is, engineer!). So at least 12 stacks of might are constantly being given by your party, even when warriors are using banners out of your fields and the mesmer does not use SoI. Furthermore, assuming the engineer is required to stack vuln, you can cap vuln without him spamming grenades only and he is able to do a rather easy rotation with bomb kit each 20 seconds, you’re now at 18 might, 6 coming per warrior and the engineer. To cap 25 stacks, you personally only have to do 7 might stacks to cap might.
Since some of the skills in an elementalists might stacking rotation have a low coefficient, including the healing skill, you can now just kick them out of your rotation to gain some personal DPS increase, while not affecting the party at all. Or you use them for blast finishers when stealthing, for whatever reason.
As this has been my main concern, I’ll not go into detail for the last few points I make and just mention what’s not realistic.
Earth 25 (full endurance) on 100% uptime. Meanwhile you already updated this to 50% uptime, which is an acceptable value, as there are some bossfights with less and some with more uptime.
Conjurer not being required. Most important trait an elementalist can chose, aside of Purging Flames and Air 25. Not only for the countless situation an FGS results in a fairly high dps increase (basically all situations, even with just one rush combined with lightning flash) which leads to the next small thing I’d like to mention: usually taking lightning flash and doing one fiery rush, is almost always worth more than taking signet of fire. Most bosses have about 1.2 million health so their healthpool fits doing 2x rush with lighning flash pretty well. Or just dropping arcane wave, although that’s a quite nice utility skill overall.
Not all targets can bleed and/or burn. I think in CoF there are quite some bosses that are immune to burning (?).
Ascended armor, ascended weapons, ascended trinkets but no stat infusions? I think anyone who can afford 800g for ascended armor can very well afford some laurels/WvW badges or gold to at least get the stat increase of offensive infusion slots, which is pretty much at the same level of damage increase as a whole ascended armor.
Last point: a bit too much theory. All this is indeed very helpful and I really appreciate all the work done, but it is a bit too theoretical for my taste. Even if editing assumptions, most builds that will come out as max. damage won’t be suitable for real dungeon/fractal runs.
Edit: I’m sorry about the formatting, I wrote the text as one response, tried to submit but got stopped by the 5001 char limit. So I had to copy and paste it into a .txt file and paste the two parts in here again. Looks like that broke something.
