Can you link any good warrior guides that go into great detail about the job? Or can you maybe provide some tips about playing war?

I'm actually going to plug @XenosysVex and @ANGERED_FFXIV here
Xeno's warrior guide(s):
good overview of the deliverance-heavy playstyle of heavensward warrior
ANGERED's warrior guide:
comprehensive guide of heavensward warrior, fracture math is a little wonky as it should compare rotations from berserk end to berserk start but it's a good guide
