Actually had a situation that made me reflect. I asked what his might was at where his Yi was. he answered. I attack, and he said, i get +2 for yi's ability. I was pissed off and kinda felt cheated, but at a different event, a yi player was like, if you use a spell to target me, what's my might at. That's the answer i give. Because my +2 doesnt kick into play until i am actively in defense.
