Summoner Question: Where should I spend my Myth tomes first?

[Flips]

At this point if you haven't been able to get any allagan pieces then you might want to consider temporarily getting the smn legs. This scenario is until you can replace them with the allagan legs. Smn legs have 34 accuracy & thus allows you to wear some of the pieces that you already have. Or maybe temporarily using the hero's belt for a small acc. boost.

I don't want to incorporate any crafted gear till after the myth & allagan pieces have been gathered. I don't think it's worth the gil to have something for a week or 2 then get your BiS & swap the gil piece out for that. Maybe it's just me. If there's some stats that I notice I'm lacking after everything is gathered I'll spend the gil & get a crafted piece to swap in. I mean with the exception of the temporary smn legs the gear in my order is all BiS so it's all needed sooner or later.

Why are you not considering Myth Belt to be best in slot? And as earlier mentioned in this thread, one piece of overmelded jewelry is best in slot.

Edit-> I now see your BiS list. Which is viewed as being less overall dps than going for higher accuracy.
