Halfswording stab is the only way do do damage with a 2h in a stabbing motion (at least for the loswords), the current lolstab is IRL so predictable, slow to perform, and rather suicide with the lolswords we have, halfswording is usefull for my polearm character when he wasn't strong enough to use his heirloom, just pick up a 2h and start oneshotting peeps with facestabs, I wonder why that never happens with real polearms though...
