the viks are a great crew because most of their models are specialists in their areas, they do prefer melee but have some great options for ranged support.
for melee you have the viks, taelor, misaki, ronin, bishop, johan and a few others
ranged you get the convict gunslinger, von schill, the rest of thefreikorps (pretty much all of them are great ranged options) and hans
the only healer you get is the freikorps librarian but she is great at it, been able to cast her healing spell 3 times and if it is on a vik they both heal the wounds due to their Fates Entwined ability. you then also have hamelin for some tricks with spells (mostly messing around with your opponents models).
a good all comers list at 35ss for the viks with a bit of everything is:
Viks
Ronin 5
Convict Gunslinger 5
Freikorps Librarian 7
Desperate Merc 2
then either Taelor (8) or Von Schill (9) leaving you with a starting soulstone pool of 8 or 7
