Funny thing is: my Whaleship Leading team (Unit 1) is an exception to that rule. It's a trigger team, and the whole idea is to kill the pests on the first combat round already. Which means, the higher ATK from the +10 rings give just that little extra.
Was a close call this time, my squad sometimes managed to kill one or two pests out of three, with always one left after a Solar Blast, but I hope to replace Apple with Iberis before the Magic whaleship missions return, that should be just enough to kill all three pests without a Solar Blast.
