Didn't find him that bad. I would've used the same party as I used them for most the game, but I had Mystic Tower (Sen-Rav-Rav) as one of my paradigms, Delta Attack (I think) (Sen-Com-Hea), Relentless Assault (Com-Rav-Rav), something something (Hea-Sen-Sab) and probably Sen-Hea-Hea.

Then just alternated between that lot. That strategy seemed to suit me throughout the game. But each person has their own strategy, so these walkthrough's boss strategies don't necessarily work. What do you traditionally use?
