Multidefeat
It's time to seriously introduce this restriction into the rules. vbn and I discussed this a long time ago, but I don't know why it wasn't implemented. The point is this: if a creature has Guard, it can only be targeted once (which is when the fact of having Guard is established).
I'm against it.
If in life, a bourgeois millionaire can bribe any guard, right? The same applies here. You bribe with 1 hero, bribe the leaders, and they go off to get drunk. The next ones get promoted, level up, and take their place. And so on until the money runs out or until you get all the guards drunk.
I also don't see the point in banning the Ballista; for those who don't like long battles, there are chess clocks. And you can always warn your opponent that the battle will be long.
I believe that the rules imply - selling artifacts at inflated prices, leaving heroes without an army (SoD), destroying castle walls with Cyclops on the tactical map, etc., and most importantly - using TE settings in SoD (I played with someone, and they gave Goshe not 20-30 skeletons, but 10-20...).
PS. Does anyone know why Bron sometimes comes with Goblins + 2 stacks of Vasas, and sometimes with Goblins + Vasas + Flies? Which option is correct?
