I do not know if anything here can help, but I have a PFS Warpriest I play as a "tanK", in the sense that he is a front-liner that I send deep into the fray.
I use the trait Fate's Favored to get an extra point on the luck bonus from Divine Favor (+2 to hit & damage @ level 1) and the extra point to my saves from being a 1/2 Orc w. Sacred Tattoo.
And the feat Fey Foundling to boost my auto healing w. Fervor (1d6+2 instead of 1d6) or my CLWs (1d8+level+2).
I took the feat Fortified Armor Training to cancel crits against me (I can auto-repair the damage to my shield w. Mending - it is 1 lb. / level, so a Darkwood Heavy Shield can be repaired at level 2).
I went 1/2 Orc and took City Raised to be able to use Whips, and chose a deity who gives proficiency in Scorpion Whips (Selket), thus being able to do lethal damage vs. all kinds of armor up to 15 feet of range (even if I only threaten adjacent squares).
So, it is Heavy Armor & Shield for AC, and being able to auto-heal as a Swift action, and boost my attacks and defence, and the whip to hit at 3 squares (took Whip Specialist for the +1 damage as my other trait) --- and simply by moving in at the enemy, I take all or most of the attacks for the first few rounds of a fight, which tend to be enough.
Does not deal crazy damage (1d6+6 un-buffed) but it quite survivable, and can help others w. Stabilize (and I like to cast Life Pact too.
