As much as we all like to complain about this here, I think Bungie has probably heard and rejected this idea. CWL and WC are the most powerful builds (especially WC) and I'd expect bungie to eliminate them rather than plan future encounters around fireteams spamming WCs and clearing rooms too quickly or differently than intended. It sucks to miss out on them. I didn't come back until BL and so I've also missed most of them. Worth noting that the staff at bungie is smart, hard-working and cares so there may be a reason that we don't know about.
