If the case is Titan, then yes… TILE Damage it is, because we need as much damage as possible within limited time.
Here is some of guide: Titan Attack Fundamentals - (new player Titan guide)
TDLR titan teams for optimal result: +att allies, -def, -def elemental if we have, +attack buff that stack like Miki/Tarlak/Ranvir/Wu Kong/Gazelle, and the rest High Attack stat strong color againts Titan.
Here is example table:
We should use 4 SLOT as the primary support to make TILE Damage as high as possible, and the rest are STRONG color againts Titan. But +att is not as impact as -def.
So, like example,…
my Blue Titan Team are: Nordri - Grimm - Magni - Vela - Miki
I choose (Magni and Vela) instead of Kiril (which he have slot for +att), but Magni has great attack stat and Vela has critical chance element link.
