Need advice about the holy mana troops

I have only three mana troops, no critical troops. Two of them are level11 and one level1. Jackal and Malosi are taking advantages of the troop+11

Leveling troops take a god amount of feeders. So is it wise from now on to concentrate on one troop or distribute the feeders on all mana troops ?

I’m CTP so the troopers don’t come so much.
