Cordovan specifically stated that actually checking things out is more valuable than theory-crafting, which is what you are doing, on something that you have barely even seen, and on something that you won't run.
Exactly. You are still making my point. You are basing your feedback on a quest that:
1) You haven't run
2) You won't run
3) It was heavily bugged.
The other R10 quest that was completed was Tide Turns (IIRC), which another easy quest that is supposed to be completable at R10, as Sev stated and expected. You have no idea of how difficulty R10 actually is.
I have no problems filling hard, when I did that recently to farm a few items. And there were a lot of Hard lfms on Argo when I logged more frequently.
