Correction: Bow doesn't shoot an so-called "Arrow Rain" when you're full charged but you can do it when it's at least at charge three (level 3 charge shot). It doesn't inflict K.O. damage but only impact damage means it's good to break parts of monsters.

Gunlance: New weapon if you moved on from Tri. It has some new moves that differ it more clearly from the normal lance like a downswing that can be combined with a Full Burst where you use all your shells at once. You also can reload one shot after you shelled one means you could use shelling endless. Also you can charge shots.

Switch Axe: Unlike in Tri the combos in Sword Mode are an up- and downswing if only using the X-button. The A-button adds a attack from the side. You can use the endless combo with other combinations (after the upswing) and it can be more easily cancelled with a dodge.

About Lance I don't know much.
