In Battlegrounds, normally on tier 6, the tavern offers six minions and one spell. However if you have the Scepter of Guidance quest reward, it will only you three minions, then the spell, then the two minions of the type, just like on tier 5 (and 4?). This is a loss in general for finding minions, especially minions not of your type. I just had a game with elementals where I had two Master of Realities, and I wanted a third but as neutrals they would only spawn in 3 of the 5 minion slots. If the tavern worked correctly you would have 4 slots and those minions would be notably easier to find.
