I'm not saying Deviljho skin isn't tough, I just don't think it's tough enough to be an effective defense against the hugely powerful weapons that most other monsters in MH seem to use.

IMO, Deviljho is perfectly adapted to hunt herbivores and things smaller than itself. It's big, intimidating, surprisingly fast and can easily savage fairly defenseless herbivores. It is much less well equipped to deal to deal with anything that can actually attack it back (which might explain why they tend to be covered in scars...).

Other interpretations are available :-)
