Some of us just completed a 4-man Coaltown expert. It wasn't easy. I'm still processing each wave and how we might change. Early on it really is a question of money vs. DPS. Traditional roles get blurred for sure. Ping me in chat if anyone wants to chat about it. The players who participated talked a bit after and will again. We'll share notes. We are going to try the other expert maps as well. If you're interested in either a difficult 4 man or very doable 5 man, message me. We'll start scheduling events soon.

I'd be willing to try any of these. I'm partial to #2 and #4. On option #4, do you mean they have to sit out the entire mission or just the remainder of the wave?
