well either way ADS is easy
i did rot method once and now i use enrage method as ADS is pretty boring boss in rot method
and to whoever say ppl who enrage kill ADS cant beat T4
T4 can be easily beaten with good tanks , strong healers & heavy DPS with prior planning on who to kill in every phase
i even finished T4 without any single caster in my party
2 BRD & 2 melee
