Corsair's Elemental Boost?

I think Air Strike would be much more helpful for training than more points into Elemental Boost. The common argument seems to be that more damage onto Ice Splitter would require less attacks for killing monsters around you. While that's certainly a plausible idea, what if you didn't even have to go near those monsters in the first place? That's what AS is for. You don't even have to go up to hit those monsters in the first place, you can 1-2 hit KO them from below. And to Daddy20's remark about training at skeles, not everyone always trains there with a mage.
