Which i119 set first?

[Ris]

Reforged +1 empy for WHM (abyssea initial source) is very good, priority legs->body->head->hands|feet. That by no means completely sets you up fully for WHM, as you'll want to acquire a whole wardrobe of equipment to get competent for +FastCast +Healing potency +MpRefresh/Tick +M.acc/M.skill -Damage Taken/+M.eva (survival) and +Enhancing potency/skill/duration items.

To play offensive SMN well, you'll want a tremendous amount of high-end farming that becomes very expensive in terms of time investment and costs of crafted material. Armors are primarily +3 AF Reforge / +1 cursed/abj. escha / augmented merlinic. A dozen or more accessories from Omen/Escha/Adoulin content/Crafting. There's a few paths to utilize for a -BP delay timers set, but getting your -BP delay timer down is significantly important for both BP rage and BP ward. As with whm you'll desire items to allocate for +FastCast +Healing potency +MpRefresh/Tick -Damage taken/+m.eva (survival) and +potency/duration related to casting/receiving a RDM or /rdm sub-job refresh cast on you.

Thanks for all the info.

About SMN in particular - it looks like the Glyphic+1 and Convoker's+1 provide the most BP delay bonuses. Would one of these sets make a decent one to start with?
