I am pretty firm in its usability, even in a tight situation. My describing it as a warhammer was only due to me not knowing the right term. The weapon itself hasn't changed. It has an axe head with a hammer on the reverse, and a spike at the top, However, it could be used perfectly well in one hand as an axe, provided he gripped it near the top. Reason being is that the weight would be pretty much the same as a one-handed axe, since the vast majority of the weight is located in the head. Try just getting a simple hammer and experimenting with the grip. You'll see what I mean. Obviously, the longer haft would make it more cumbersome. There are certain ways he wouldn't be able to move it due to the long haft. And he could not have allies behind him while using it in this manner. Overall, polearms can definitely be used in close quarters with the right grip. It's not preferable over a shorter weapon, obviously, but long weapons don't suddenly become useless if you close in too much.
Of course, Ssarak probably won't be using his poleaxe anyway. It makes much more sense just to pick up the glowy axe and use that.
