That's what is generally assumed, and similar rulings have been made as far as feat pre-reqs go, but I think that would be sort of a house-rule. I figure that since the totemist at least has access to 3+ natural attacks, he should qualify to take the feat. Still need to have 3+ active to use though, and not all of them can be used together on a full attack.
Anyway, I'm trying to read through SiFi's Incarnum Handbook for tips on how I might go about making an effective build. Hobgoblins are mentioned as a good race, but recommends trying to get the DM to lower the LA to 0 since it's barely better than most other LA-0 races as-is.
Sunscorch hobgoblin would allow me to use draconic soulmelds, which are generally nice additions, though aren't necessary. The regular hobgoblin's got better stat bonuses anyway, though stat-wise Fire Hobgoblin's even better for this build (though even with certain 'melds, might not be the best option if mid-ocean ends up in LoI).
The downside is playing a monstrous race might not be easy to explain in-game.
