Hm...
For yuni
I guess someone who likes yo fight close range could be useful as he/ she can lure the target to the trap and the traps can help meleeists
Maybe Volray would be useful as he can effect the field with walls as well so easier to lure and he technically could launch people as well into a trap
Maybe it could be a team of mêlee and traps XD
Its just a sugestion for now trough
