Giving this a little bump because I popped in on Odessen four times in the last 24 hours to poke around and see if anyone wanted to run Star Fortresses. No luck so far.

I agree with these. I suspect part of why supposedly "noone" runs some of those content missions anymore is because finding a group in the first place was hard, or it was annoying to have group content gating the end of an otherwise solo quest chain. The "Heroics" earlier in the Macrobinoc/Seeker chains were roflstomp easy I face rolled through them in a mix of Corellia/Early Makeb gear pre-SoR as a merc with no idea on what my role was. But the last Heroics are not soloable like the ones before it.
