I've been going GNB in roulettes and we can survive and I tank just fine. Not putting any additional stress on the healer because I see most dps a lot. I'm a healer main so that probably helps. I don't panic if they let me get low since I know their capabilities. Only had issue with a WHM in a Stone Vigil run only casting Cure so I just dialed pulls back.

WAR is kind of fun for the "warrior is immortal" meme but I feel like I earn it a bit more with GNB.
