Hmm.
For Bardin I guess these are for me the sensible options:
-
Hammerer
Equipped with a runic hammer. Difficult what role would fit. Lorewise a real Damage-Dealer. -
Runesmith
Sounds cool, but a pretty ancient role and Bardin suddenly turning out as one would be odd.
It would be a very good Support-Role tho!
Nothing else would really stand out.
- Maybe a Dwarf Engineer?
Or give him a damn Gyrocopter, that sounds fun.
