A whole class useless? I still regularly get shot for ~50 % of my HP in one arrow when I'm using 52 BA (15 str, 4 if). The archers in cRPG are definitely weaker than in native though, but deservedly so, ranged in native are a joke just how strong they are. There's literally projectiles flying anywhere whenever you visit a native server that isn't siege or duel.
I doubt that cRPG players who's not used to native would do well in a native tournament unless they have someone who's already familiar with good tactics, drops etc. like Teeth stated. It's more about tactics than impressive feints or being good at fighting outnumbered. Speaking of which, fighting outnumbered in native is pretty retarded with the polearm overhead dropping the shield for a brief moment, making it borderline impossible to win, even with a shield.
