Yeah, that character… kind of needs to go back to the drawing board.
The steps to make a character go:
1] Find a skill and damage type you want to use and invest maximally in it with skills and items.
If you want to use Righteous Fervour and auto-attacks, that means maxing the first two nodes, getting a lot of WPS skills to 100% proc chance, and getting items that add damage/improvements for both.
Currently you have invested a low amount in your main attack skill and have not taken any of the 3-4 WPS skills (Zolhan’s, Markovian’s, Smite, and Shattering Smash if you use a shield)
Unless you’re going for a retal build, then you won’t need the WPS, but in that case you haven’t taken the Righteous Fervour upgrade (Retribution) that adds retal damage to your attack…
2] Get your base stats up to snuff.
You need sufficiently high resistances, hitpoints, armour, offensive ability, defensive ability, attack speed, and sufficient sustain like life steal. (Caveat for linked stats: they’re for older patches and no longer apply 100%, but they give an idea. Get more hitpoints and OA than the guide recommends, and less armour/phys resist)
You have plenty of armour, and your OA and DA are acceptable-ish (you really want much more OA for a physical build to trigger your RR devotion) but all else is lacking, as others mentioned.
Best way to do this is to get some legendaries you want for point 1 (stuff that supports your main damage skills) and then farm some useful greens to cover any gaps in your stats. And don’t overlook crafted level 90 items like boots and gloves. Even though they’re yellow items in the blacksmith menu, they can roll green affixes and can be very strong options to cover gaps.
3] Cover the remaining gaps
Getting things like CC resist, abilities that have “reduced enemy damage” on them, making sure you have some circuit breakers. But those only really come into play in endgame scenarios, in the campaign you’re mostly fine without them.
Others have already mentioned how to search for items. In your case you may need to make some hard decisions, though, as there really isn’t very much to support physical righteous fervour. You could consider swapping for a different melee damage skills like Blade Arc, Cadence or even Blitz. You could also consider using a different damage type, but for warlord physical makes the most sense.
Oh, and the upcoming patch should help you: it is set to greatly reduce monster armour and should make physical damage builds much more effective.
