I don't think you understand; I stopped playing 2p Small World (Digital) long ago mainly due to Ghouls. It is EXACTLY like playing a 3p game where your 2 opponents decide to only attack you for the whole game.
As for your combos, Flying Sorcerers are a highly randomized combo; it really doesn't matter what Ghouls are paired with (except maybe Merchant because of the low unit count.
Simply put, Ghouls make it an imbalanced 3-player game where 1 counts two races and there is not a lot of ways to counter this. Other combos are merely happenstance that can be chalked up to bad fortune.
I would like to one day play 2p (digitally) again with this one important fix.
