A career or single-job SMN could have some fun with this. DT-10% and Regen makes for a solid tanking piece, Haste for TP or general melee. I don't know if I'd want to give up 7 Summoning skill for Crit+3 though, I'm still hurting for BP acc on P.Claws in general.
Don't forget the BP Timer -3, either. Matches Summoner's Horn and Penance hat. So... maybe we can forget it. :P
SMN's biggest problem is, I think, we don't do enough of any one thing. Especially career SMNs. Our avatars can double as tanks, especially VT and down, but that doesn't happen all the time. We don't melee all the time, a good chunk is summon-BP-release. About the only two pieces I'd see getting the most use is Haste (since you need TP for magic, and general melee is never bad), or Crit+3 (ignoring the AF Horn and just solely looking at the augments).
Honestly, I'm intrigued but underwhelmed. The DT-10% and Regen are interesting, especially considering we can't get them anywhere else.
Also look! Acc+3!
Edit: Also remember the Cure+3%. One of the few non-pet augments that, you know, work for us. Another ~10 HP is never bad, especially if you have WHM, RDM, or SCH.
