Ill explain some stuff about my suggestion for polearm/two-handed axes/one-handed axes to be more common and more variety:
1 Good reason for it to be implemented is that not everyone had enough coin to buy or even make a sword.
2 Even though some axes were actualy pretty expensive and not everyone had a handy small war axe for one hands, Axes were still pretty common.
Anyway the axe that would be fun for devs to add is a dark age axe: http://bladesmithsforum.com/uploads/monthly_01_2011/post-26987-129494690272.jpg after all axes should be alot more common, but swords should be more worth than it already is and it should cost more for someone to carry a sword, anyway.
3 It is the earlier version of Danish Bearded Axe, remember that we are not in 10th Century but 8th, stuff are slowly processing, that would be the ancestor of Danish Bearded Axes, most people think vikings used axes the most but actualy Saxons and many other cultures used the axes more than sword aswell, not only for its cost but it was actualy really effective weapon for its price, as many said in the earlier comments sword were really expensive too, it was for people with high status, the higher-end soldiers, kings, earls, jarls, nobles, ETC. For a commoner a sword would be impossible, maybe if that commoner scavenged from the killed enemy.
In anyway though, everything can wait, i would rather have a fixed DLC than having new stuff added to the sadly bad DLC(i like it though, bad in a way that the bugs and glitches ruin it.)
