Okay I decided to drop the doppleganger idea. If it wasn't for the RHD I'd be more down for it but 6-8 levels are too high a price to pay for a +4 AC and a weak detect thoughts.
I decided to try some variations on Striders FrostBear build suggested above. Tome of Battle is out so no swordsage and I have to be careful to avoid multiclassing xp penalties. I have two ideas here, please help me weigh the pros and cons:
I get 1 free LA so I'm going for mineral warrior. LA buyoff is allowed.
Note I haven't figured out the order of the progression yet so advice there is helpful.
First thought is to be a Goliath, Barb 1 (Pounce, mountain rage), Stoneblessed 3, Deepwarden 2, FotF 1, Bear Warrior 5, Frostrager 5, Warshaper 2, Cleric 1 (Animal Devotion for more strength or flying which handles that objection to VoP).
The other idea is to just go Dwarf (Mineral Warrior), with Barb 1, Deepwarden 2, FotF 2, BW 5, FR 5, Warshaper 4, Cleric 1.
The goliath gets more strength and Con but will lack the ghost touch ability of FotF 2 (due to VoP synergy) and the extra reach and fast healing of WS 3 and 4.
The Dwarf won't have as much strength and con but gets the benefits of being able to hit ethereal things plus the reach and fast healing.
So...which would y'all recommend?
