I'm sure you guys get alot of these. I rolled a Human Barbarian, and then I chose Bastion of the Outland. Turns out, this was a VERY bad idea. I am currently level 5, and what I'm asking is:

Is it too late? Should I reroll? Or can I be saved? If so, can someone point me towards a build I'd be able to follow for a good THF barbarian?

My stats are:
str: 17 +3
dex 10
con: 19+4
int 8-1
wis 8-1
cha 8-1

134 hp
AC 19+2
Base attack bonus 5
fortitude 10
reflex 3
will 2

Thanks.
