I picked up DRK again this morning for the first time since getting it to cap about a year ago. My big question: Why on earth is there a timer on the job gauge showing you how long living shadow is active if there's no way to make him stay longer AND his presence doesn't change your gameplay at all? That seems so weird to me. I'll also throw these ideas out there while I'm on the topic:

1. Make Shadowbringer a GCD.
2. Shadowbringer consumes 20 seconds of darkside and keeps Living Shadow out for an additional 10 seconds.
3. Add some passive effect to living shadow. Maybe you generate blood gauge faster, maybe you take less damage, maybe your mitigations last longer, or generate more MP, something like that.
