So I think it's worth going for a mix of the 2, no? Melee has the advantage of being able to hit incredibly hard and have a strong block..Together with the fabulous thanes this makes it pretty strong.
Unarmed however has some very, very good bonuses. The incredible fast rate at which IP is gained for example and I feel that these 2 are best combined with each other.
What would be the best ratio for it? 1 ua for every 2 melee? 2 ua for every melee?
Oh, and slightly related and not worth opening an entirely new thread for. What is as of now the (estimated) max. hit of the best ranger's bow in game?
