A +3 DGS with 7 PS (just as an example) will already only be doing an average of 14 damage to that (assuming a neutral speed bonus and no hold bonus).
With that suggestion, you could just make a 36/3 greatsword/glaive character and never stop swinging. You would only need the 25% glance chance to trigger once to get a free 12 PS hit in (enough to one-shot many squishier builds, and two-shot decently armored balanced builds), through no fault of the opponent.
