Team Composition Help

Hi I haven't play in quite sometime, but I have 6 characters lvl 153 across 2 accounts.
My question is are this combination of characters anything good?

Sacrier, Eni, feca, cra, cra, cra

I Do love my Cra's its simple to play and I don't have big setups to do before I unleash their skills, Sacrier is also the first character I did so I would like to keep him, Eni seems to be necessary because of the heals but sometimes it just feels useless and I'm not sure about Feca, I had him before as a tank, but now he looks weak for that role, any suggestions?

Should I keep eni and feca, do a class change, I also have a sadida and panda lvl 125, maybe swap for one of this classes ?

I will appreciate any feedback guys. thank you
