Idea for a techmarine perk to regen some ammo: Forsaken Munitions

Just spitballing, if techmarine had an ammo regen perk I think it could be cool to tie it to the tarantula sentries.

Maybe activating a tarantula sentry (not reloading one) restores 1 magazine for the primary weapon.

I think it would be a bit lazy and boring to just copy heavy's prestige perk of getting ammo from extremis melee kills. Plus it's mainly effective in lethal/absolute where there are more extremis anyways.

I really feel like Techmarine could just use a decent, consistent way to get a little ammo back.

What do you think? Obviously I think he needs some better knockback resistance too, but besides that this kind of thing is high up on my perk wish list.
