Yes the original intent was for healing marks. But it has several other advantages...which are nothing to scoff at.
+1 ac
+1 to hit
+1 to all saves
Access to Halfling Guile enhancements for more S/A Damage.
Access to Halfling Dex
Access to Halfling Luck Enhancements for up to +3 more to each save
The warforged has power attack Enhancements
thf glancing blows
immunities while being
harder to heal
-1 to -3 less to hit. (if I forgot something sorry I don't play trees lol)
So boiled down...
Halflings are a little more survivable and better at Sneak Attack Damage... Warforged are better at direct damage.
I think I still would have gone Halfling just because I like them better, But its all a choice, I have seen a few WF versions that are pretty cool all around.
As for quarterstaves... yep.. I can't find them anywhere anymore... they used to be easy... last time I post a build I tell ya...
Oh and the deciding factor of swapping out was when I finally got the gloves from Titan, so I knew I had reliable self healing. To some folks the ability to self heal is no big deal so they wont mind at all.
