So I was excited to see that they were going to +2 the AF to make them the same as that of RUN and GEO... Sadly... >_> They still suck hardcore.
Let's start from the top
Convoker's Horn: It's a great boost to DEF, MP, +SMN Skill, +Enmity, -BP Delay, and Refresh. This piece is great in comparison to the Emp. Horn+2
Convoker's Doublet: So, Maybe I'm out of touch with it, but the whole point for SMN, I thought it was to maintain the avatars for as long as possible. Why would I want to give up -4 to Prep cost for a boost to magical defense abilities? SMN as Dream Shroud, Phalanx, and Avatar's Favor for such a thing. Which again the - to BPs are nice, but what's the point if I have to recover more MP to actually use it... (Also why would SMN need EVA, we can't dodge things anyway...)
Convoker's Bracers: I have always hated these things, ALWAYS!! The convert DMG of avatars type almost never procs, but why would I fight something with the actually element VS its weak element? Let alone, be in close enough combat to get hit? Plus with the added things to Magic DEF means it would do less DMG... which also translates to less MP covered anyway....
Convoker's Spats: These are somewhat solid, and offer the Magic DEF+ stuff, -BP Delay, and MP. I don't mind losing the +6 to SMN Skill
Convoker's Pigaches: -4 Prep, check... boost to the Avatar's evasion, check... Boost to all the other things Magic DEF related, check.
Also, I've gone through, and looked at most of the RoE weapons, Again, nothing for -Prep costs... SMN put a lot of work into making those Trial Staves for the - BP Delays and -Prep, why ignore that hard work? >_> And I feel it's about time for a trial to make those staves into one staff. Requiring the Staves to be the tier III versions and then makes a staff called the Channeling Staff or something like that.
And while I'm on the subject of upgrading SE should look into upgrading the Evoker's Ring, Yinyang Robe, and other equipment pieces.
