Questions about Heroes

1) Can we buy them new armor? If so how?
2) Is not being able to dye their present armor correct or a bug?


Note about Heroes: do not give any of them your all time favorite weapon. The tend to go walk about and take said fav's with them. Then you are SOL until they are rescued etc..

LOL

...then rescue the Hero. It's only two freaking quests.

You can win new Hero Armor through the Challenge missions.

And you can't dye the armor.
