Need help to improve/optimise build

Currently finished the main acts and have done some mapping, up to about T3 so far, don't have too much trouble with most mobs (so far) but, I'm also having trouble doing old league content i come across (Legion, Blight, Abyss to name a few).

I'm trying to avoid dual wielding and stay sword and shield, is s+sh viable for endgame?

PoB:

Main skills used right now:
Molten Strike (dmg source)
Molten Shield
Flammability
Ancestral Protector (attack speed source)
Rallying Cry
Leap Slam (mobility source)
Blood and Sand (Blood stance)
Anger

I also left other gems i used the most during acts

p.s How do you change the title of spoilers?
