You say Lucy's stupid for underestimating Gemini... when did that ever happen?

Sure she didn't use Gemini often, but that's due to their nature. They aren't a pair you just summon in the middle of a fight. To use them properly you need preparation or get into the right situation for them to be the best choice.
