Valkyr is warframe's berserker character, harnessing her searing rage to dismember and mutilate enemies with vicious efficiency. Valkyr is a very consistent and powerful melee warframe. With a sweeping array of enhancements for her melee weapons, and a powerful melee transformation ability, Valkyr is ready made a melee oriented player. Speaking of that melee transformation, Valkyr's keystone ability unsheathes her vicious claws to tear enemies apart with massive damage. Valkyr is also rendered completely invincible when her claws are unsheathed. Clearly, Valkyr is an excellent Melee warframe, but her limits lie there. Valkyr's gameplay can't push past a melee oriented style, and for that reason, It makes her hard to recommend to all players. However, If melee gameplay interests you, you could hardly do better than pursuing Valkyr.
