Heh, I found out after a longer than expected first encounter that a Gigginox is not exactly a Khezu. Slapped on a Poison Negate armor and got him on next try, but things are definitely getting more interesting.
While waiting to get the materials for some new GS, I've been using a fire-element Switch-Axe and really getting into the weapon type. A fun compromise, sort of a wide-swath LS switching into lighter-power GS, with overload that reminds of the GL shell. I see why this one is popular, once you sort out what mode can do what and when.
Edit: and yeah, having gotten used to the swimming controls and the benefit of boss click-targeting, I'm getting along quite well with this game on 3DS
