allround hard-hitting wemic build (paladin/hs/assassin)

Now that wemic and brownie races can be selected (and discussion on the forum is moving in the direction that this will not be changed any time soon) I have been playing around with them to try and find new viable builds. I'll be posting some of the more interesting ones on the forum. I'll be posting this one in phases, so expect some updates.

This build tries to use the wemic 'large' size to give builds that were previously just hitters some more survivability.

Key aspects:
1. Wields a great axe (or any other large weapon) as well as a tower shield
2. Maxes dodge ac to get an 'ok' armor class
3. Adds 65% conceal, which should greatly improve survivability
4. Have some useful utility skills at decent lvl (search, open lock, umd)

Cons:
1. Must start as a paladin, so Gondor only.
2. Only 5 attacks per round (but at really good ab, so most will hit)

Starting stats:
str 23
dex 9
con 11
wis 14
int 14
char 12

Race:
wemic (duh!)

Feats:
iron will (harper scout), power attack, divine might, divine shield, expertise, knockdown, extend spell, weapon focus and improved crit great axe.

Epic feats:
great charisma III (2x harper scout bonus feat), epic weapon focus, armor skin, prowess

Hints for building:
take 8 persuade on paladin lvl (class skill)
take 8 hide/ms on assassin lvl (class skill)
take +1 charisma as first stat improvement, to enable divine might/shield feats

Lvls (final: paladin 17, harper scout 5, assassin 18):
1 through 16 paladin
17 through 20 assassin
21 through 25 harper scout
26 through 39 assassin
40 paladin (for discipline)

Estimate of final stats:
ab 69/64/59/69/64
ac 75 (easy) to 78 (with really good gear)
quite some irresistable dmg (divine favor + might)
