Sadly, and as shitty an outlook as this is I do believe you are correct.

I mean no one wants to spend a ton of time on one thing. Crota and Templar maybe you won't need all 6 people, but no one wants to do Skolas for 6 hours

No joke. Spent a couple the other day (my 1st full hearted attempt). We got to him fairly quick but after a few ammo/ failed "for real" runs we needed a short break (you know how it is being a grown ass adult and not wanting to wet your britches). Come back after 10 minutes but the guy who was keeping our spot in airlock was booted from game world so we all lost our progress. Has me thinking I might not care to try again for a while.

Yeah. I would do it once and then stop. The rewards are not worth it

Thanks. Seems to be the consensus. They couldn't at least make so if you used a key on big chest maybe an increased chance of an exotic. I mean something. Sounds like even lackluster rewards aren't guaranteed. All about the tactically useless bling.
