This is why I wish there was multi-player to play against guys like jshores who understand simple math (3-2 = 1), but not opportunity cost (3-clumsy = 3).

That is a rather disingenuous and insulting thing to say.

I understand the opportunity cost and I understand that you can "work around clumsy" and gain the +3 attack. What I am saying, and really it shouldn't be that hard to understand, is that these two skills create a no choice situation if you don't plan on taking another weakness. You're sitting at 0 points, you have not checked "Might" or "Weak". There is no sacrifice for taking these two traits together at that point. That means, there would never be a situation where you don't take a weakness, at the very least, you would always take "Weak" and "Might" to maximize your character.

don't think that combo is broken or unbalanced. if you want to play a sov that is a physical damage dealer (warrior/assassin), you'll probably pick might, but you'd be silly to also pick weak, since that's the one weakness you really don't want. if your sov will be a spellcaster, commander or tank, you probably won't pick might, since the small bonus to attack is meaningless and there are better alternatives for trait/item picks that make a lot more sense.

i can't really think of a build/plan that benefits from picking that combo.
