This time got visited by Xyrella, who wanted to do the Serena Bloodfeather (Normal) bounty with Tavish… and also Deathwing, which is of lesser signigicance here. Anyone remember the Book of Mercenaries? 
Maybe it is random, but I still enjoy it.
Technically, bringing Scabbs there might have been an ‘anachronism’, if such a thing exists with all those timelines, but I think Millhouse was also a perfect addition, if anyone remembers the Mercs ‘tutorial’ (I actually looked that quest up).
[UPD 19/01/2023]
Got two tasks, both for the Chess Event (Normal): one from Drek’Thar, with Niuzao and Illidan in the party, and another from Bru’kan, with Kazakus. Funny, but actually managed to do both in one go, adding also Trigore to the party.
Such challenges — and I haven’t even been writing down all of those interesting tasks — make you think sometimes that there is so much more to this game than your tried and true go-to parties or even original recipes…
