Let's talk Dark Knights

[Liam_Harper]

Living Dead is fine in a group that knows what they're doing. In a PUG, it's a crapshoot whether the healers are paying attention and know what to do. Solo, it's delayed suicide, because DRK doesn't have enough self-healing to deal with it.

Even if the healer knows what to do in an organized group, if you use LD to immune tank busters you're either holding the WHM's best single target oGCD hostage or you're demanding a bunch of resources and/or GCD healing. Living dead is rubbish in any group, it's simply inferior to any other tank immune.

Invincible moves are used to cheese or make fights easier, but nothing in the actual game requires you to invu anything or it fails.

It's a piece of your toolkit. There are a lot of abilities in player toolkits that aren't absolutely necessary but are great because they make life easier if we utilize them well. The simple fact is that if 3 of 4 tanks have a powerful ability to handle tankbusters and the 4th tank has an inferior weaker version, that tank is comparatively worse off than the other tanks, even if they're "fine". A class can be viable but still bad.
