Living Dead QoL buff

[Kelg]

Please make Living Dead have visual ques, 99% the time healers don't even know when I use it. I know I can make a macro, but it seems to me that a skill like this that requires so much coordination should have UI elements to it.

My ideas for living dead visuals:

• Make the Tank's HP bar change to black and white color effects and sounds to indicate that Living Dead has been activated
• Once the Tank's HP hits 0 and walking dead is activated make the HP bar pulse red until they are healed enough
• Minor: Have Living Dead's cooldown be partially refunded if Walking Dead never activates

Since people brought it up, some ideas for actual buffs to Living Dead(any one of these would be nice, but not necessary):

• Increase potency of healing spells while in Walking Dead by 50%
• Add 100% Lifesteal to all attacks while in Walking Dead to help heal HP(would be nice for solo content too)
• Get brink of death status instead of flat out dying if you aren't healed enough
  
• Make the buff apply right when the button is pressed(Hallowed Ground and Holmgang too)
