Is it intended to be useless?
It's essentially useless when we can't rely on a minumum duration on the anchor. I've anchored, poofed out and tried to poof back and anchor was gone. I've seen a 2min duration on it maximum, which is fine. Also it seems to disappear with zone repop, which is also fine and removes the instant repop/skipping parts of zone issue.
Just please up the duration, so it can be relied on? 2-5 mins seems fair to me
