No, Courtney is correct. It’s the best body piece for all the situations that she listed listed.
Why do you need enhanced fast cast for casting Refresh and Haste? Both spells are usually cast in cycles, and assuming you’re able to stick to this cycle there is no reason to cast these spells any faster or reduce their recast times, when compared to just keeping the Dalmatica on. You also mentioned healing magic; do you even play FFXI?
Crimson Scale Mail does not replace 2-3 body pieces. Many items that RDM uses on this slot are situational; having a Convert piece (for which personally I feel W.body is only suited to Tarutarus) does not mean that it will completely replace other pieces. I’m going to assume you’ll still need whatever body piece you used to convert before, you’ll still need hMP on body whether it is from Errant or Yigit and there are certainly better pieces to solo with. Replacing certain roles and replacing items altogether are different things. If you used AF/AF2/whatever to convert before, you’re probably still going to need those items. Also, while meriting I don’t see how you can think Crimson Scale Mail is better than Dalmatica; there’s no reason at all to take the Dalmatica off.
Lastly, have you even fought wyrms before? Judging by the fact that you seem to think -10% to breath attacks is useful, I’m going to say no. The only reason I see for using AF1 body is to enfeeble, most of the time it’d be ideal to either be wearing AF2 to reduce Stun recast (with DRK sub), or Dalmatica for MP regen. It'd really help if you gave half a thought to your posts in advance, instead of looking at item stats and including them all, useful or not.
