Revenant buff

I have an intresting idea!

Revenant Rework:

Tactical
-Silence should deal 12 damage
-Silence should completely disrupt enemy communications instead of negating the victim's abilities: the enemy team shouldn't be able to see the victim in the map, to see their status and to talk with them via voicechat or ping system
Cooldown: 30s
Effect duration: 10s

Ultimate
When revenant activates his ultimate he becomes (not his teammates) a shadow and drops a death protection marker (maybe a skull). If Revenant takes fatal damage he will return to the death protection marker. Revenant can return at the death protection marker leaving shadow form at the cost of 99 health.
Charge time: 240s
Range: 80m (current: 60m)
Duration: 60s (current 20s)

Shadow Form
Shields are disabled
Footsteps are silenced (even when running)
Max wall climb is 20m
Healing is negated

What do you think?
