Yeah EA is all over the place with displaying errors. The combat log is more accurate.
I'm pretty sure she's only +2 from Dex because of finesse, but the damage die means her average DPR is better with a rapier.
She's not optimized in EA. I've seen a couple of different builds for her in videos of 1.0, some showing a Str build, other a Dex build. Though it might just be level 4 choices.
SH gets a bit MAD if you try respec'ing her to be Wis/Str/Dex and Con.
