I'm playing Dwarf.
You really need your feat slot for resilient CON.
War Clerics are not terrible, but the Light Cleric I've played felt way more awesome and synergised better. Better damage, better bonus action economy (Clerics have a very busy bonus action), better channel divinity, better wisdom based ability, less MAD.
If I wanted a divine frontline fighter I'd take the Paladin, Tempest or even Life Cleric over the war cleric, and that's why they're all tier 1, and the War Cleric is not.
My ideal party would actually look something like this:
Fighter/Warlock.
Lore Bard/Life Cleric 1.
Wizard (Abjurer or transmuter probably).
Paladin.
Light clerics don't have the AC without further investment and adding the light cantrip for free isn't really a winner. The domain spells could be worse but direct damage spells don't keep up with hit points. The domain ability doesn't do a lot of damage either. The big draw there is flare and it's a defensive ability.
The +10 to war domain abilities are also on a reaction and offensive so a high damage hit doesn't miss, but admittedly it's a key moment ability more than big damage. The weapon options do more damage than the cantrips for the light cleric so better blasting doesn't seem like much.
War domain spends a feat on magic initiate, 2 on WIS, one on CON resilience, and one on heavy armor master, and runs a high AC build with staff'n'shield plus avatar of battle for defense over offense while relying largely on spirit guardians and spiritual hammer for solid damage. It's similar to other clerics but more survivability and less likely to lose concentration because of the avatar ability. The alternative is to skip Heavy armor master and the magic initiate feat for STR at a defensive cost and run higher at-will damage than the light cleric.
