The thing is people should not be mad if someone DOESNT bring Shirk!! I have dipped into the Savage content and V1s doesn't even need a tank swap. matter of fact a lot of the content in this 4.x doesn't need a tank swaps per say like they did in heavenwards, but its still early in stormblood so who knows. I do use Shirk and I agree it is a great ability. my thing is that people shouldn't tell someone they have to bring it and people shouldn't clown someone for using it thinking they are bad tank from what I read on the forums. Its a good skill BY NO means is it required but a great skill and if you run with a static or looking for one most likely you will be using it, if not and just play in groups at you own pace and still get things done its not needed but again great skill.
