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.
The level cap in EA has skewed some people's perceptions. If SH focuses on STR or DEX she is not going to be an effective cleric at higher levels, and she isn't going to be an effective fighter either since she doesn't get Extra Attack (her cantrips do increase in damage - but without maximising wisdom they won't land).
