well, it might be desirable to use sellable price from a faction stat to determine whether to buy something from the neutral AH (i.e. for BTM). cross faction arbitrage, basically.
you wouldn't want to comingle the scans themselves, though, certainly.
I would very much like to be able to compare the neutral faction to my normal faction AH specifically for checking the potential profit of an item. Is there some way to switch the current faction setting without going to the AH again? I can't find one though I'm still searching the site here and the wiki.
if you are in a neutral zone[and not at the neutral ah] you can toggle the 'show home faction data everywhere' on and off (its a toggle in advanced > general options)that would let you basically toggle between both the neutral ah tooltips or home faction tooltips... Theres a jira somewhere floating around to add some method to see opposite faction tooltip or value but don't think its being actively worked on atm
The way I've considered doing this is to have an "Arbitrage" stat the shows the data from the other side... Or the neutral prices, or maybe whatever the highest of the 2 factions is (because that's the price you need to beat in the neutral AH, not the lowest price)
And/Or an EvalArbitrage for BTMscan (which there was a rough version of to start with already).
But I haven't been playing with the neutral AH for a while, so I didn't do anything more than think about it a bit...
I can't find my local copy of EvalArbitrage. I moved development from an XP box to a macbook pro... and somehow managed to flub my rsync of my codebase. Linkage to EvalArbitrage? It was all of, what, three lines of code.
*so* much shame.
Edit: Found it. I had misspelled "norganna" in my google search: site:norgana.org arbitrage eval.
