That is pretty much what I'm doing as well. Also used the exp book for the first time.
Wol and cloud to 50 and rotating in third characters, have a chain going well with wol at 42 cloud 36 and bartz at 32, so can progress nicely.
I've pulled almost exclusively on the weekly banner and now have
Wol sword limit maxed
Bartz sword limit maxed
Cloud needs one more sword
Also have 10 4*s, limited character overlap
And 9 unique 4*armors
Wol cloud bartz terra I have both weapon and armor.
Then rest of gems and tickets netted me:
Rem
Terra
Vaan just now.
Summons focusing on
Sylph level 7
Ifrit Shiva 5
Odin chocobo 4
Ramuh 3
I just run sylph for healing. Not sure if that is ideal or not
