How would you improve the Paladin's Cover skill?

[Katish]

How about something like this:
Cover: Will allow you and the person you are tethered to survive with at least one hp during the tether. Does not consume your hp if the person is hit. Must have a target to use and that person must be within 10 yalms. If the person moves out of range, the tether will break early. This will allow Paladin to have another mitigation move, but also allows it to be usable and have a niche that allows someone else to survive with you. (As long as there is someone) Might need to change the cooldown of this skill to be higher as it becomes more usable as a "second" invuln, maybe 420 seconds like Hallowed Ground, as warriors are able to use Holmgang every 240 seconds. So in the time u go from one into the other, should you need it, warriors could have used Holmgang 2 additional times. (But allowing someone to survive has value in of itself so it makes up for it imo). It would be usable to guarantee someone's safety vs intervention where that's not always the case. Example: If your other tank is down and a DPS or healer is needed to take a tank buster this would be a saving grace.
