don't think your english is bad, it's fine if english isn't your first language, english isn't my first language either.
back on topic, so maybe they should get a unbalanced factor, but not the one we have right now, because that one is to much of a nerf for them.
because in the beginning, the morningstar had crushthru ability. and believe me, back in november 2010 the scary morningstar (morningstar +2 with 41 pierce) had greatmaul-like crushthru potential. (weapon 4.5kgs with 11 powerstrike and 200wpf, no steel shield +3 was able to stop it bypassing the block).
that was WAY too overpowered because with that weapon speed (93) was able to mantain block/hit/block sequence against all but katanas. and the 41 pierce with 11 powerstrike was a 1-2hit fest on plate tanks. (remember that pierce do x3 damage to the head instead x2 for cut and blunt... so by using only overhead swings, 1hit kills were more than often.)
the devs then removed crushthru ability (instead lowering it by lowering damage and weight) for the same reason they did later on barmace.
i know... polearms have the bec de corbin. it's a better "can-opener" than morningstar. polearms also have better shieldbreakers. but polearms lacks the best crushthru weapons (mallet and great maul... even the base maul is fine with 9PS) and the best dueling weapons.
a good thing we often forget, is that barmace and morningstar, by their heavy weight, often stuns the upper block on lighter weapons. so a good way to use them is to hold a overhead (to stun the block)and quickly release a right to left aided by waist turn.
i was thinking to retire a morningstar too someday. is really good with 24/15 or 27/12 builds.
Your English is fine.
well thanks. i just don't know how my english is. sometimes trolls troll my grammar.
