Living Dead Tweak that would really help things

I think Living Dead is an outstanding skill, the problem is not enough healers understand how it works. I feel like it's not even worth using in most cases due to the risk of wiping the group. Even with an alert macro that it's coming to give the healer a heads up and time to prepare 1 of 2 things usually happen, either they smash you with heals and it doesn't pop and they waste all of their strongest CDS trying to keep you alive during the skill. Both usually result in a wipe because after they can't sustain without all their CDs they burned. Other than alerting the healer in advance there isn't much more you can do to help the situation besides just not use it unless it's a trusted healer which significantly sets you apart from other tanks in some dungeons.

The two things I think could be done if it's possible to completely remedy all those issues are.....

1. Make it so when you pop Living Dead until it is concluded you can only receive healing from yourself.

2. Make is so once you activate it until its concluded, whenever you are target for heals it sends the same message as when you target a friendly target with hostile skills "This is not a valid target" kind of thing this would physically stop the healer from being able to freak out and blow all his CDs even if he doesn't understand the skill.
