I disagree on t1 Overtime, I've done a lot of runs in mainly blues (and greens) and it's all doable.
My Princess killing methods - BM tanking and MM kiting:

As BM you don't need to max range boulder (the NR aura loss means more dmg on pet) you can Mend Pet after if she stuns you. Even now with my 3 piece I don't bother maxing. If you run out of mana just switch to cheetah and drag pet away, run her around a bit, heal up pet and get back to it.
If you're MM kite as in the video. It's a bit boring but it's good to know how to do this stuff.
Rotgrip/Landslide I would forget if you're MM. Go BM for Rotgrip if you need the boots or take mana pots.
