In my situation, I tend to wield Halberds, simply for added Strength, and that can do a lot in Close Combat against enemies like Ogres. against skaven, elves or the likes I keep to handweapons and shields.
well, I tend to lead from the front with my Life-slann. that way I know my enemy will think twice about shooting artilery at him ^^
the +1 armoursave from the shields is really usefull against skaven and dark elves because then they'll have a 3+ armour-save in Close combat, and a 4+ in ranged from the Dark Elves. So tailor it somewhat to your opponent and you'll have yourself a blast ^_^
Heh, you probably should have read the whole thread. You can't choose any more, you have to always fight with Halberds. The topic is waaay old, back when we still had 7th ed WH.
