So before i show my list, i'd just like to say that this is not a list of the MOST UBER combinations EVAR. I made this list based on what type of characters i'd like to have on the field.. so dont expect 6 myrmadons with 6 paladins or anything like that.
My goal was to have every support being a class that complimented the lead character in the pair, along with the ability to have S rank support AND support boost+ and support block+ for the other skills on the supports, you can fill in the blanks how you see fit. Anyway, so after doing some searching for a "Best combinations topic" i couldnt find one.. and there isnt really anything i could find so i did lots of research and mix-n-matched all the possible parents and heres what i came up with.
