id say drop plummel and put more into frenzy.
never do that
at higher lvl pummel is amazing, my weak lvl 39 pummel can hit over 2.3k out of 2418 dmg (would increase it's dmg, but cant find my damn royal pummel)
well in my case with using heavy damage weapons the damage ive seen from plummel isnt quite impressive as a lvl 1 giant swing. :/ but i guess if plummel skill damage is getting you more damage than a weapon damage based skill then go with that. I forget not everyone uses 2handers lol
heavy wep is different, no pummel if using ymir hammer or any 2 handed wep
one handed wep? use pummel
