As BLM I've actually had healers /comfort me right after the tank dies and the tank buster switches to me, then I just type "sigh" in chat. Is that my reward for being highest DPS, death? I"m starting to see why people ask for more utility and defense tools on DPS. If I make a mistake and get myself killed I deserve it, but what is the point of the highest DPS dying due to tank mechanics?

I've had co-tanks run to me on accident with the tank busters and I just mitigate. I don't see the issue with the other tanks soaking another tank buster, we have a lot of defense cds for a reason. I will say tho I love that the tank busters in nier raids hurt so much, but that also means most casual tanks get one shot because hey don't use cds anyway.
