There appears to be a bug where there's nothing to do on the Broken Shore.

Currently there seems to be an issue affecting players were there isn't shit to do but grind paltry amounts of nethershards from the few mobs that don't get greyed out to you by esoteric tagging rules. Also the towers are apparently taking about 10 times a reasonable amount of time to level.I can't seem to find a blue post on this unfortunately.
