Go to the runemaster and use 4 runes to get specific runes - dwarven steel and dwarven armour. You don't really need to worry about regen on those in comparison to others. Might cost a bit of gold though.
You could also use 4 runes and swap them to get specific runes for other classes. Keep them in the shared chest. Comes in handy for classes you might play later where you wanna pump up CA - e.g ghost meadow, infernal power, heroic courage, testosterone, etc
P.S - trading at 150 for a level 67 character is pretty neat.
