Team Comp Question

I finally feel like I have a good problem!

My current team setup is Adept Jansen, Master Wu, Agrilla (who will soon be replaced by Marlina, who I am leveling), Nexara (awakened) and Mogh Grut. I just summoned a Merila.

My question, is whether or not it is worth trying to fit Merila in the lineup, and if so, in place of who, and why?

Any insights here would be appreciated.

Use it to replace Agrila, you have three tanks at the moment and generally only need 2 and 3 support characters. (Mix of Hunters and mages.)

I am in the process right now of replacing Agrilla with Marlina, who I have already, but who needs a little leveling.

The options for using Merila would be to replace the awakened nex, mogh or marlina.

it goes down to which type of hero do you have evo-material for. Most people stick to 2 hunters, 2 warriors, and a mage as it's the solid damage per attack team (2 mages dealing massive damage on CRIT). Merila doesn't need to be added as you have an awakened Nex who will outshine in damage UNLESS you pump mage evo mats into Merila and level her up AND THEN awaken her.
BUT if you have a lot of mage materials after getting Nex to shield rank (or whatever you find comfy) and are finding you can only evolve Marlina (over Mogh, she's better) you can swap her in for Mogh.
It comes down to "Who can I make better faster" which unfortunately is determined by random number generation when getting evo materials each day

Thanks so much, Soda! Great response.

I have a glut of hunter mats, so I'll be sticking with Mogh for now...but I'll hang on to Merila to see where things go in the future.
