In a build with Cleric 2> Priest 3> Chaplain>? > Taoist … what would be the best option for rank 7 instead of miko? Build facing the pve only. Some people have recommended me Kabbal, oracle or Cleric 3 … what do you guys think? 
I tried to do the missions to release the NPC Miko Master but I gave up, it’s not for me. I do not have the patience for that sort of thing.
Sorry for the horrible English 
I’d say PD for the debuff protection~ Extra heal, and extra DPS.
Pure PvE you probably wouldn’t need Kabba… Priest 3-Chaplain you’re probably full SPR, so Ein Sof won’t be as useful to you (only useful when partying others), and R7 isn’t as amazing in PvE. Kabba isn’t bad for PvE, it just doesn’t seem it’s the best choice for you as a simple rank 7 filler.
Oracle is a good choice too~
Oracle or Cleric 3? 
If it’s between these two only… Oracle.
And Krivis, for Daino?
Ora is better for bossing. Just bring Daino scrolls
Kabba 1 wouldn’t be worth it, in my opinion. Your Merkabahs get destroyed way too easily from enemy attacks as Kabba 1 (need Kabba 2 for the durability attribute) and Ein Sofs duration isn’t that great either at level 5.
Miko, despite being annoying to get, is really worth it, in my opinion. Mikos Gohei and Hamaya are still quite strong, despite the nerfs.
If i had to choose between Cleric 3 and Oracle 1, i’d choose Oracle.
With Cleric 2 and Priest 3 you have very good healing already, no need for Cleric 3. Oracle on the other hand gives you immunity against common status effects, you can change dropped items and can use Counterspell.
