User blog:Reentear/Been away for some time, need help with squad rebuilds

Coming back to Brave Frontier after a heavy hiatus; last I played Avant, Silas, and Sirus were major leader units. I'm sure the squads I have set up used to be good for general content, FR, Hard Content, and Raids, but at this point I'm just not sure if they are good anymore. I've done a bit of summoning since being back so have gotten a number of new (to me) units.

While I'll mainly list the units I have that I think are worth mentioning or brand new to me, I have something over 400 in my stock so ask if I have one you know would be very good!
