The only thing I would want to ask him is about the TotS BOB issues, and this would need to be worded carefully. Allow me to explain.
We're having a specific issue (there's about a one in five chance that no BOB spawns on Tip of the Spear) but it's not necessarily his area of expertise. In my mind, this is THE issue right now re: BOBs. There are different ways to count the number of BOBs, how to number and organize the BOBs, and so on, but that's largely moot. Since I'll be wiping out each and every BOB spawn in Reach, on Legendary, in a full-run no-death game where I read all Data Pads, it doesn't matter if there are 10 BOBs or 49 BOBs. I'm going for completion, so if what I'm doing is overkill it's not a big deal. But, if we can't find a BOB, that's an issue.
Since we can repeatably predict the BOB spawns on every level except TotS, I believe we're aware of the BOB spawns with the exception of that level. Once we get this particular issue cleared up, it won't be too long before I can complete the BOB guide and determine, once and for all, if anything happens if you wipe out all the BOBs on Legendary.
In short: I believe the missing Tip of the Spear BOB is the last significant BOB mystery, and I believe we should make some effort to get assistance there.
