Khaini's Empress Attempt

Perhaps, but if you look at the minimap, you'll see pretty much everyone die right around the same second as that 50k hits InFearNFaith.

As for your party setup suggestion.

aran, evan, bam, drk, pally, se.

Not sure what the aran is there for. Evan is good, we wanted to bring one but they were unable to make it. Evan would be good in any party though, probably better in ranged party because they can atk from a distance, and use that mp heal cloud thing. When I was attacking, I potted almost exclusively for mp, because I had an awesome bishop.
Bam is good for ada and shield, ideally one in each pt but whatever. Shield is beast.
DrK, who wouldn't want hb? But most of us have self hb. What I noticed was that the instructors and their summons were doing sub 10k if you didn't like, walk into them. Meaning you're totally safe if you have a bish (speaking form ranged), so ranged was pretty much golden without hb (all have self hb or enough clean hp), and thus the drk can be in crashers pt.
Pally for CO and threaten and all that tanking ability is invaluable. As many as you can get is still not enough, lol.
SE, melee party doesn't need se. The SE should be in ranged party with a bish.
Shad, smoke is lovely. Shad should be in melee party and Bam should be in ranged party. When it's time to let empress out so she can summon, smoke would be fantastic. Imo, a shad in melee party would be a great addition.

Here's the problem; ultimately you need these people to exist. How many 19x Shads do you? Evans? Arans? Legit BaMs? Even dropping the requirement to the minimum level 170 it's tough to find a couple. Then finding some that are competent bossers, can follow instructions, aren't idiots that'll steal any loot that may drop, the number of potential runners drops. Include that ideally you want a bish in each party, how many bossing bishops do you know that are 17x+? It's reall tough to find these people, and enough of them.

Personally, ideal parties would be 3 pallies, 1 drk, 1 shad, 1 bish. 1 se, 3 nl's, 1 bam, 1 bish. 1 se, 3 nl's, 1 bam, 1 bish.

However, that's not really a realistic scenario.

The only problem with Evans is that Blaze's range is BEYONDDDDDDDD terrible. You would need to stick them up close because thats how we attack with blaze.
