Are they? I mean, most of the WoL's fights involved being part of a team - usually Adventurers or the Scions. Rarely did they face a foe 1v1 - and one, (in)famous example of when they did was Zenos in 'In Crimson It Began' - and he kicked our ass!
And I certainly got the impression that the WoL wouldn't have beaten the Endsinger 1 on 1 if it had come to that.
