Are you thinking that you get the 485% AR bonus of Fire Claws even if you use Maul? This is not the case; the 485% bonus only works if you use the skill Fire Claws. If you are building a PvP Mauler I can't see a reason why you'd max FC; there are no physical immunes in PvP (only 75% block and 50% DR, and skills like Bone Armor).
Actually I do like the idea for PvM; a FC/Maul hybrid:
20 Lycanthropy
20 Maul
1 each Hunger, Shockwave, Werewolf, Werebear, Feral Rage
20 Fireclaws
rest in FC synergies (about 30)
Equip an upped shael'd Ribcracker and you have enough speed for both attacks.
The choice between Oak Sage and HoW is a personal one; it's an ongoing discussion.
Why not just max Werebear, get passive damage bonus, and JUST use fireclaw. The +skills from 1 pt maul should be enough to make by the few occasions you'd need it. Good idea with ribby too
I don't think 1 point in hunger's worth it... it does so little : / Just my opinion
Slothkin, the best kodiak imo prolly isn't a kodiak lol. I'm in the same boat as you, my opinion of maul (other than just charging up a hit or two for stun in pvp/pvm) is not a good one. It takes TOO LONG to be effective, the AR is horrible, and the list goes on. I think you're right about using Fireclaw with oak in PvP, however it's sorta an all or nothing thing to me. If you're gonna do it, you might as well synergise it to get your bargain outta it, you wont regret it

The great thing is, you could easily do something like this:
15+ firestorm
20 fissure
20 fireclaw
20 lyc
20 werebear
1 maul
1 oak
And still maintaining the same Kodiak gear: highlords, fortitude, griswolds caddy/Grief (5-6 fpa), SS, Gores, bloods, etc.... you basically lose almost no damage that you had before. If you think about it, you'd have the same initial passive physical damage except you'd have the awesome AR from Fireclaw and an added ~7k Fireclaw bonus for kicks

I think it'd be pretty cool 'cause even in PvM you'd have a pretty awesome physical damage base from Werebear, Fortitude, ~50% deadly strike, without even having to chargeup maul much or worry about its crap ar, so you can just focus on FC which would be some awesome versatility. I'm not saying that maul can't be used ever, it can still be used to chargeup from quilrats or town, etc, but that's about as far as its effectiveness goes in duels.. when most duels last only a few hits. Food for thought
