When you asked the dispatcher if the reroute was "terrain critical" how were you expecting them to respond? Did you specifically indicate that you were asking about critical terrain in regards to a depressurization event? Maybe the dispatcher thought you were referring to the grid MORAs. Or that you were questioning the drift down altitude capability with one engine inoperative and the need for enroute alternate airports?
Simply put, when you have a flight routing that puts you in the brown shaded areas of the Critical Terrain Orientation chart, always load the escape route in the secondary flight plan/RTE 2. Put the Escape Point into the PROG/FIX page and plot the 80nm ring around it. Don't expect the dispatcher to remind you to do this kind of planning, and they certainly aren't going to do any of it for you. Like CamYZ125 said, the charts have instructions on them. Use them!

When we swapped seats with the deadhead crew (who have flown this route before) taking us back to CLT I asked if and how they plot depressurization routes. Got the deer in the headlights look. Thus my decision to take this to a wider audience.

In addition to the other information you'd receive from C&R.

Neither of us had ever flown a route requiring it and have seen it only one time in the sim.

You're conflating two separate functions, single engine terrain clearance and depressurization routes. The former is primarily a dispatch function, the latter a pilot responsibility in flight.
I don't mean to sound harsh, but if you're that murky on the subject you should probably reach out to a checkairman/the training department.

The consensus is this is the wrong place for this thread, so that's it for me.

Are you using the LUS charts or the new ones? I haven't looked at the new ones much since I got off the bus last year but if your route is 10000 feet or below you would be fine not doing the depress routes. We used them a lot out of PHX since almost all our routes in Mexico went down the Sierra Madres. I liked the new charts when I saw them.
If you are off airway just use the 80 mile circle to figure out where your nearest entry point should be.
