Mecanic 2nd skills

I second this. Rocket Booster is useful to an extent, but setting up portals saves time and makes going back and forth round a map much much faster, hence increasing your %/hr

On maps that actually require it. There are next to no maps until higher levels that even remotely use portal.

I left points out of booster. Though now that I'm 4th job, next SP reset I'll be leaving the points out of Heavy Weapon. I saw no reason to leave rocket unmax.
