Why was Living Dead not removed?

[Shougun]

Just off the cuff maybe something like this ...
Hallowed - duration 8s - recast 420s
Living Dead - duration 10s - recast 360s
Superbolide - duration 10s - recast 360s
Holmgang - duration 8s - recast 300s

I feel that's a strong nerf to Paladin's Hallowed Ground, since they lose 2 seconds, have the longest cooldown still, and they can't be cured during the duration. Coming out of it with hp (from healer heals) is quite helpful when moving to the next step of something.

Especially if you casted Hallowed Ground later in your HP pool, come out of it with sub 15% hp and then evaporate because the healer wasn't ready for that millisecond cure lol. I think that just introduces potential frustration to HG (beyond not triggering when you cast it right away xD). Strength of Holmgang in the changes depending on the frequency of tank busters, since it's the lowest it could still be #1 (especially if Paladin's lasted just as long and they couldn't heal up during it).

Maybe if their clemency was buffed or something during Hallowed Ground? (and could cure self). I think bringing the cooldowns and durations closer together would be good but I don't want to see the can't be cured applied to Paladin (and the strength of a low cooldown I hope is recognized over the casual "OP" appearance of Hallowed Ground, Holmgang is one of the most OP of the four impervious skills).
