Caller's Set seals: smn solo?

[Texx-sylph]

considering all you guys said, i think the first thing to do i to build up a good set of Atma's.
i'll start with the basic ones trying to get
Ducal
Minikin
Mounted Champion

i know this set is not the best as a dmg output but i think is the staerting point i can use to solo something in abyssea. Yesterday i started my dominion ops on Graub and as a 95 smn/sch i see all the mobs (also che #1 ops) as even or more... so i need desperately some atmas... and some abyssite (in particular Merit and Furtherance ones)

and yes, i re-started playing @the end of Feb with very short time to play (new type of exp and achieve goals make me return)...
i think with this 3 atma's i can start doing someting and start also trying to solo some other mobs that can grant me some other atmas (beyond? Apoc?)
as i miss all the caller's set... what's the first pieces (in order of importance) do you think i need to start for upgrading? i was thinking about doublet+1 ....
