I dont think sword and board users are op, and I dont think 2h/pa are either. they are all fairly well balanced for their class types. In the end it all comes down to personal skill and knowing when the strike window is with the equipment you have on.
Im a 2h player, and fighting SB is always a challenge. stay out of the spam zone, spam in return
at the range intended for your weapon. Look for feints. if they close with you, you are dead (if they are any good). that seems pretty balanced to me.
I like to do what I am supposed to do with my class anyhow: break up fights that are already happening. kill my teammates opponents. ambush archers.
2h Ambush funPlay smart.
more than one turtle + me = run
one turtle + me = fight
