Īll the same considerations from solo apply to group play, so Marauder DH stays the best.

If you want to stay alive, then stop fighting at around wave 120-122 and run away from mobs to get overwhelmed.

If you are playing Softcore and don't have pools of reflections stacked, walk into a meteor as soon as you reach wave 125.Click Conduit Pylon, Channeling Pylon and Power Pylon at wave 70-90.

Click Speed Pylon instantly, since it's gonna last the whole run anyway.In that case you use your pylons a bit differently, trying to maximize your power and spend most of the run oneshotting all enemies: The alternative way to approach Echoing Nightmare is speedrunning to tier 125. Some builds use cooldown skills to deal damage so Channeling Pylon is a major DPS boost for them, in that case you click Channeling earlier together with Power. The idea here is to buff yourself up with Speed and Power pylons when you start struggling and then when even those pylons are not enough you let Conduit do the work, while Channeling lets you spam defensive and mobility skills and stay alive.
