However, I think the Sirius set change is just fine. A skill attack every round seriously imbalances the whole game in so many levels.
Yep. Similar games have evolved to where they became too easy / too OP, to the point where they lose their luster -- what made them shine in the first place: the challenge.
If I wanted to eliminate challenge, I'd go play FarmVille.
