Survivability perks

Ok so the vanguard has a perk that gives him 10% hp back on a magor or higher kill from a melee attack or an execution. So for starters this perk should be on the assault class as an option as well as the vanguard. This would give the assault survivability if players choose to use this perk.

For the tactical heavy and sniper as they are more range based than melee i was thinking of a new perk that they could have as an option. This new perk would give them 10% hp back on a major or higher kill from a ranged attack or gun strike kill. if players choose to use this perk it would give ech class tactical heavy and sniper more survivability as they would be able to recover hp slowly with out a player being forced to play bulwark. If some players dont want to use this perk then they simpley just wont equip it keeping every one happy.

I do not think the bulwark class needs a version of this perk but maybe adding the option might be an idear just to give players more perk options to choose from but like i said i dont think the bulwark needs 10% hp back on a magor or higher kill from a melee attack or an execution as they have there ability.
