Melee characters have significantly more CC abilities than archers whos ONLY CC ability, without putting points in other areas, is pin down which is just a cripple. Warfare has 2 knock downs a taunt and a cripple, they also have 3 mobility moves to get them in their enemies face, while huntsman only has tactical retreat if they need to get away from an enemy.
A 2hander with 10 levels in necromancer is extremely tanky without needing much constitution, this is what ive been using to solo, no companions at all and ive only died once.
