The Nu Gundam is amazing. Last Shooting is 800 points more powerful than Funnels, but Funnels have an added surround boost, and the Psycoframe boosts Amuro's evasion to insane levels. It also boosts his critical rate (on top of what Newtype gives him) and SP gain. Oh, and Nu has a max range of 5 (Funnels+Bazooka) instead of 4. So...if Amuro's not an event character, and you've etiher filled up your group slots for deploys or the stage isn't a group stage to begin with, Nu is probably a better choice for deployment. The thing with Amuro's group is that it has Anti-Air, Anti-Ground, Anti-Space, and Anti-Large attacks. Last Shooting is regular piercing instead of barrier piercing, so you have to watch out for doubleimage. That's why bringing along the Axe Bomber (for Daunt) isn't a bad idea; it gains SP really quickly and Cocoa has a high maximum due to her passive, plus she has an AoE Hit+Dodge boost with a max range of, I believe, 5.
