I'd recommend FTR 20/WM 7/Rogue 3. It nets you an extra 1d6 sneak attack, a few more skill points, and Uncanny Dodge (you'll probably only get +1 DEX bonus to your AC, but why not keep it if you're caught flat-footed?), while that 21st FTR level doesn't really do much for you. Start with Rogue at level 1 for the extra skill points (and you can also get your Initimidate requirement filled right then).
You'll lose 1 AB this way, so you'll have to decide if it's worth it. _________________ It's rogue, dammit, ROGUE!!!
Thanks! Btw, do you guys think it will be good at PvP?
I'd drop search and pick up spot instead. If your not an elf your not getting the auto check and you do not have disarm traps. Or pick up blind fight.
Your build does look nice and like it would be fun too play.
