Hero Class

[Looter]

It depends on how you play, if your an ative fighter you will contribute more as a legionaire or zweihander. Personally I love my Huscarl [not legion, cough] because of his all round ability to fight in nearly every situation where a zweihander usually is mentally bound to using a 2 handed and an eg just kind of sits there and shields. Of course though, action is up to the player but anyhow, since it appears you are concerned for money, go zweihander or RG since they are cheaper to properly equip than a legion, you need more gold for one.

Tl;dr:
-Legion more Expensive to equip, Zweihander/RG cheaper
-Legion Versatility, Zweihander dmg, RG shield
-How good a class is, it's up to your playstyle [ex. A useless after will not help even if hero]

I may have some grammar/etc mistakes so mention them if you see them.
