So if anyone is curious @Ston's pointers are basically going to get you max damage. Enflame is an aura that, kind of like Shocking Field, is doing damage while you and your pet do whatever. A pet is also doing damage while you do whatever. The Mace pet in particular has the Achilles' Heel proc available, so there's 20% more damage for its duration. Enflame can also proc Annihilation, which is another 12.5%. In his video you'll see him use Inferno to potentially proc Fury of the Gladiator for another 20%. If the stars align, you will be doing a lot of damage very quickly.
At some point, -res kind of gives you less bang for your buck, so you just need more raw damage. You can snag some through various set bonuses. It may or may not also come from Assault Core, it has a 65% chance per attack to go off. In our 1 minute time span it should essentially always be up, bar the ramp up period. More attack will come from Bio Armor. Fire Armor also gives damage, but not as much as Bio and I don't think the nerfed version of Burn will be enough to offset that.
So once we're past those variables, we come down to the Primary sets you use. We don't have to consider damage type since the resists are a flat 20%. So anything is technically viable. I'm currently fiddling with what we'll call a heavily modified version of my spreadsheet that has to throw out averages and assume a lot of "up-time" for buffs and debuffs to give numbers even remotely close to Ston's 48s run there.
It looks like your rotation is going to have you using Pulverize and Envenomed Daggers basically every other attack, so you're largely just using one of your attacks out of your primary. Pulverize gets a lot of procs and Daggers has a very high DPA on its own and is affected by global damage and recharge bonuses.
That's before and after using Aim.
So assuming very high recharge because we're using just horribly broken builds that are focused to this one task, it's on a very short recharge. Geas alone is giving you 100%, then another 70% from Ageless, and 70% more from Hasten. You have a lot of recharge for 1 minute, and you only need 45s worth. So like I said, 1 single attack from your primary, and your Tier 9, obviously. Because it gets you access to Fury of the Gladiator. But only for certain sets.
Now we can throw out Archery, AR, BR, Ice, Seismic, Storm and Water because their T9 is a targeted AoE. You may be saying also Electric, but it has the additional pet, so it might have a chance. Also, these sets might be able to pair with Fire Armor because Burn can also get you FotG, I haven't checked. What I have checked is just having FotG anyway. Here's who doesn't hold up assuming Fire is the baseline with the dirtiest math available, using their highest DPA attack.
Archery, AR, BR, Dark, DP, Energy, Psi, Rad, Storm, Water.
So we're left with Electric, Fire, Ice, Seismic and Sonic. This is also assuming Ice and Electric have found a way to get access to the FotG proc. Technically Electric can use Short Circuit, but that's massive drop in damage output from the start with it's 2.5s activation time. So that might not work out. Ice has absolutely no way to reach it without switching to Fire Armor and using Burn. Doing that drops it out of the running. So Fire, Seismic, Sonic are left.
Blaze is massive DPA, Gravestone is apparently enough to keep up (and you can cycle in Stalagmite when it goes off), and the same goes for Screech.
Do with this information what you like. Maybe the quick, dirty math is wrong.
