Here's a first attempt at a STR-based BC:
SNIP
Builder hasn't been updated for U19 yet: I used Diplomacy as a placeholder for Spellcraft (since both are class skills for clerics); then just did a search-n-replace. Since you're LRing a lvl 20 build, I'm presuming you already have at least WIS +8 gear, otherwise I wouldn't dump WIS like that. [If you don't, then some
Commendation farming so you can pick up the Cleric or Villagers WIS gear might be in order.]
Typical melee BC: buff up, swing your weapon of choice, spells are mostly for heals & light-based DPS. Kiting thru Blade Barriers is still an option, though DCs will be lousy. I'd make Radiant Servant your primary PrE - bursts, auras, etc. - but enough pts into Divine Disciple to pick up Nimbus / Searing Light SLAs. The only must-have from Protector (soon-to-be Warpriest) is Divine Might.
The first few feats are kinda iffy; apart from Power Atk & Cleave, there's nothing you really need. I would've preferred more metamagics, but not an option here. Thought about the full THF chain, but that would mean losing a couple of metamagics.
Anyway, have a look and tell me what you think. If you want WIS-based instead, that gets a bit trickier, but can be done; just not sure your DCs will be worth it.
