um ive beaten titan quite a few times with pld whm sch drg drg brd blm/smn blm/smn you dont need to stack classes/jobs to win i have never had more then 1 brd in my pt at any given time just need good players who know how to dodge.
i have dealt with class stacking in 1.0 not going to deal with it here thus im not gearing blm or brd for me atm i either go drg or not at all lol
