Hoarders do NOT spawn in same spot as the regular bloodguards. I had 4 Bloodguards and 3 Hoarders spawn at same time in that little room so I can promise you that.
The hoarders pop inbetween the bloodguard. So with full room pop of 7 no more easy single pulls you get 3 at least. If you keep the room clear though you can single pull the hoarders.
