Darth Revan who?

I question pretty much everything CG has done in the past few months. Power levels of most of these new characters is out of control. And I think the future looks rocky because of these stupid characters. But nest is on a unique level. Why would they think it's okay to give a character stacking, undispellable protection, making her unkillable under certain circumstances? A ten year old could tell you it's a stupid idea. There should be a cap of perhaps 3x on the ability.
