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.
