T2 may or may not be easy depending on the group and the method used. You take T1 ads, make 3 of the same with one new attack each time, then big boss. Big boss uses the skills of all the mini ones you didn't kill, and the make-or-break move here is the allagan rot. If your group can pass it without problem, the fight itself is easy. If not, then you won't win.
Enrage method allows to burn the final boss without caring about the rot though.
