closseum setting

i have some problems in setting my team in colosseum,i seen something in official forum a file exel but i didnt find nothing updated with new weps,armor,boots ecc.
is there something in official forum i didnt found or f there is a simple way for setting it?
for now i understaned this (if someone have better idea correct me pls )
tank and healer :put all best stuff in defense
range and melee :put all best stuff in attack
(i think there is other way but i didnt find nothing more easy of this way )
thanks for all help and ideas

Ive been trying to figure that out for awhile but I do the same as you lol

I usually just spread everything out. Of someone gets a noticeably larger bonus from something then they keep by default.
