Absolutely.
The majority of 2h weapons also need crushthrough.
(depending on weight and length)
Actually that would be pretty cool. There's a crush through threshold in the game, so it wouldn't necessarily be unbalanced. If I remember correct, any item with a weight under this threshold has a much, much lower chance of crush through than the ones above. Even if they do the same damage. Currently in cRPG it's 2.4, but if we increased it to something higher, then the normal 2h/poles would have be able to crusthtrough, but only on the REALLY high damaging attacks and only against the really light weapons, while the mauls would still have enough weight to be the same as they are now. Not sure if i really want this, but it would be fun to test it out. I remember they had this in WFaS and the only time I managed to get a crusthrough was with a claymore on my cheating character and with a pike on one of my normal characters against a blocking horselancer. Guess it was mainly because of the speed bonus on the latter and the lulz damage on the former.
