Long bardiche isn't so op, u should learn how to play with it first.
morningstar is a realy good weapon, with good balance damage/speed/lenght, just continue to loom it.
if u want any good polearm weapon - let's loom bec de corbin, long hafted spiked mace, gla, long hafted blade or poleaxe. those weapons are good too.
but it depends on you, your playing style and your preferences
