Infighter vs Gunslinger

I have read these builds, but i said we won't see either of these skills MAXED. Atleast not for a while. Having windbooster at lvl 11 early though does sound good, since any higher only increases time.

Devil keeps talking about a 6 viper party for continuous Super transform for all 6 members, but wouldnt that require all 6 members to have max time leap + max super transform?

I see what you mean. But you dont max Wind Booster, ever. Its not worth it. But max Time Leap does take a backseat to other skills, yea
