What power level is t2 Peridea Patrol intended for?

so in t2, i ran it for hrs trying to complete it with g11 enoch and death g10 night all at 5. got pissed and ranted making a fool of myself.gave up hope of completing it then decided to try auto, i watched as the computer made decisions that i wouldn't have.but.... somehow it pulled off 3*.  it made no sense at all. there's definitely issues with the game but t2 is doable with 5* toons.
