I found it a bit awkward that the buggy can break some unbreakable walls, but it can't chop tier 2+ materials in nature.

It would be nice for the chop power to scale up with the Omni Axe at least.

Sometimes I am gathering materials with my buggy, and then I face a tier 2 material, and I need to get off the mount to chop it and then go back to load it up.

I know buggy mutations are in the road map, and something like the power upgrade can be present. But for now, scaling the chop power with the Omni Axe level should do the trick

Most likely they will add Black ants for tier 2, fire ants for tier 3 etc.
