It's actually really good. The only problem with it is that it's only good minimum item level and the areas could be connected up more to reduce loading screens because PS3 isn't supported anymore.

It's not going to be be removed because it's a part of the MSQ now.

It's your own problem for doing it a lot. I don't do it and I can't see a reason why it's necessary to do it that much, even for relics, because there are alternative ways for relics. I don't even normally get it in Mentor Roulette.
