Because as of now the only way to get your health back is either
A. You're a Titan. And i think Warlocks have an ability in their Subclass too that triggers Health Regeneration? not sure
or
B. You have Red Death or Suros Regime and not everyone has these weapons seeing as how everything is random.

[b]Leon1des Says: "You can regain health with all characters as long as you have raid or exotic armor that give you health"[/b]
I'm aware but there is no guarantee you'll get any of those doing anything

[b]EDIT: I've been informed that all classes have the ability to get health back when they add the right perk to their melee's![/b]
but i personally still believe a Gatekeeper should drop a Chalice in case that person would rather use a more useful perk in that section of their skill tree.

[b]EDIT: I've seen some people say yes but under the right circumstances. And i agree here are some ideas[/b]
1. The Chalice could be timed! meaning it wouldn't last forever
2. If the person holding the chalice dies it will disappear. Meaning you'd have to kill another gatekeeper.
3. The Chalice cannot be shared and can only be held by the first person to pick it up! Rules 1 and 2 still apply.
