Always going to turn the tide in his favor with those advantages.
That said Polearm isnt a "I win" button against dagger users, what it does it give you added survival bonuses.
Laesron had some nice logs beating up dagger specs (though, to be fair, that was before they nerfed the pincer staff super hard). And I stole that build from Arrna (Deriveh) basically.
Brondalorm had a decent amount of success against everyone but Nazarates using polearm as well (though, again, to be fair, most of my success was switching to maces and spamming drum).
