So, it's not a half-measure, but an expansion of possibilities.
P.S. Of course, in War of the Throne, the game on a mirror map almost always featured the same heroes – the strongest in that faction. Gosh, Broghilda, Valeska, etc.
Moreover, it's worse than simply banning top-tier heroes. Because even if you start with the same heroes, if one gets Gosh/Luna/Jeremy/etc. in the tavern, and the other doesn't, then it's obviously unfair.
Therefore, if you're going to duplicate heroes, you should duplicate all of them and mirror the tavern.
