Help with my new Warder

Hola, I have decided to play GD again after a long pause. Made this warder -
I have no idea what shall I do now with my devotions, skills or which items to get or whether I should change them all. Can you help me please? Im in act 1 elite with no problems, but cant make it past crucible 90.

Shouldn’t you have more skill points into the class masteries for stats? And get that armor rating and absorption up, it is quite low for a lvl 51 melee char.

This is more important later on, but resistance reduction from Wind devil -> Raging tempest, Rhowans Crown/Manticore (Rhowan and manticore resistance reductions do not stack so choose one), Widow and Viper (this is not as important as the other ones)
