Think about it. This could be the next best thing for all DoW classes.
Make it so that it has a long-ish cooldown like 4 minutes. Can't be spammed but it will be there for what really matters.

Even better, gate it behind a content you really want people to try- Golden Saucer prize, LL DR daily. BAM, influx of every serious player into those contents.

SE can go as far as making it tradeable so it becomes the next Ehcatl Sealant.

Why isn't this a thing SE??
