engineer ability

thinking about things last night and I think that an armour blast artifact might be needed or useful. the medics can heal their pets with a healing blast so it only seems right that engineers can repair their creations with a blast as well. I suggest having the shield blast continue to work as it currently does. a 2nd artifact for armour blast would be added that would heal sentinels, turrets, and vehicles. sometimes in a heavy battle, if I stop linking the turret, the turret will die. this means I can't heal the sentinels that are taking damage. if the defense sentinel dies then more stuff comes through and we all die. an armour blast would fix this problem by letting me heal all at the same time. or instead of a blast use a armour sphere to heal them over time. this allows all constructions to be healed over time if your link is occupied keeping a turret alive.
