You want one AW for sure to tank enemies and cast Pull of the Abyss. I prefer Keeper over Elementalist because of her Disruption Field and Static Cage not to mention better Shield passives. Either Alchemist or Archer is good for the Rogue spot and I would take Templar over the other heavy armor just for the AOE stun and massive amount of damage boost she can bring. So my Ideal party for Perilous would be:
1. Arcane Warrior
2. Keeper
3. Alchemist/Archer
4. Templar
On the topic of Katari, if you have the level 23 unique Greatsword, then he can be pretty good in Perilous as well.
I honestly have no clue how to play Alchemist in gold, can take maybe 2 hits before dead without barrier,
and very long cooldown on the important skills.
Will try some more, but seems to me it might be lacking in that difficulty.
My choice (until further testing),
1.Legionnaire
2. Elementalist
3. Elementalist / Keeper
4. Keeper
Heavy: Legionnaire, no questions asked. Until everyone's geared and speeding through content ME3 style, bringing people who guarantee a clear is very nice. Templar's good, especially as a second warrior, but has very little survivability in my experience,
Medium: Archer. So much damage, good safety too. If Hunter had Long Shot or Mark of Death, this'd be up for debate...but he doesn't.
Light: Elementalist. That massive stagger and chain-panic potential is invaluable. His CC--which comes with tons of damage--is so good that you don't need Barrier. That's just...mind-blowingly good. Plus he has arguably the best passive in the game.
Our perilous loadout is: Legionaire, Keeper, Arcane Warrior and Elementalist/Necromancer.
And the Necro seemed to work even better than the Elementalist. Dat Walking Bomb.
Templar, Elementalist, Necromancer, Hunter.
Class combo galore.
