I'm going to be joining a Wrath of the Righteous game that's currently @ level 3- I expect it to go to the end of the AP- 20 with mythic. The group currently lacks anyone in heavy armor and the only heals come from a MC'd inquisitor.

So I want to create a melee-centric battle-priest, using either a greatsword(preferred) or sword/axe/etc. and board if the survivability hit outweighs the extra damage. 25 point-buy, and I've narrowed my choices to:

Both are Human or Half-orc

Cleric of Gorum Uses a Greatsword, has to take heavy armor prof. Plan to take Ironbound Master, power attack. Domains would be Glory for the spell list and Destruction:Rage for the Raging ability. Will be pretty feat-starved, but seems to have a lot of potential and full caster progression. Crusader helps with feats, but the loss of spells/domain hurts

Warpriest of [Milani?] I wanted this to be a Warpriest of Gorum, but from what I've read Warpriest leans reeeeally heavily on the summons from the alignment blessings 10+, and I'm worried the Chaos summon monsters won't hold me in good stead in WotR. Milani seems ok, probably taking Good and Liberation. Iomedae or Torag would also work, though I'd rather avoid Iomedae if I can.

I haven't played PF in a while, so not sure what if anything I'm missing. I love all the cool stuff the cleric gets, but I'm worried the lack of feats. Warpriest has the feats and the amazing Fervor to get spells out fast, but they seem to lose a lot of spellpower and lack access to the raging/glory spells/Ironbound Master Feat. Champion of the Faith would help potent this up some.

Which would be the most effective?

A secondary question is- would 1 hander + shield be much better for the melee cleric? I'm not interested in a lancer/archer/reach build.

Thanks!
