Bloodknight

Tactics
This is a great damage dealer. His job is to charge towards low HP enemies (especially backline) and quickly eliminate them. Life leech gives him a lot of sustainability as long as you are in melee range and dealing a lot of damage.

Beware poison / bleeding especially from ranged units.

Once you get stamina to 90+ (charge + normal attack) put points on STR to maximize your damage.

Also remember that greatswords have mediocre shatter value, so armored targets should not be your priority until other team mates strip that armor.
