It would be great if we had sticky regen & dmg bombs.
Sticky regen bombs could be tossed up at mountain cliffs, up into trees, etc.
Sticky dmg bombs could be tossed up on cuttletrunks, future bosses/titans/etc, up into trees & rocks to clear an area, etc.
Sticky regen/dmg grenades would be basically the same, but they would have a longer range and smaller action radius.
A sticky light flare would be useful for cave exploring & night hunts.
