They're not suggested; they're an "interesting choice". Suggested has a green aura around the flag in the select screen. Gawed and Lorent are the suggested nations for Cannor.
If it's MP they stand no chance against a player Gawed, that's a given. In SP I've played Redscale (basically the same) and they're not that bad. You just build forts and knock them off only when they have a chance to take it. Eventually they'll bleed so much that Lorent or Grombar attacks them and you can go in.
Really this is like complaining that Castile is too strong because you can't beat them as Granada.
Edit: Sorry if this came across as insulting. I didn't intend to say "skill issue", I was just trying to point out that some nations are supposed to be harder than others.
