If you can stand the diet (cheese, fruit, fungus), then they're just fine for solo'ing. They have less DPS than cats, but more survivability. However, they have more DPS than boars, but have less survivability. They're well-rounded.
If you love the way they look, pick one up! Level one to 70, even. It's just that if you plan on doing end-game raids, pick up a Ravager when you get there.
