It’s just too simple a ‘get out of jail free’ card if ships can press that button in combat and be invulnerable to fire.
Imagine fighting a group of bombers. You lock one, try to shoot it but it cloaks. You lock another one, try to shoot it but it cloaks too, while the first bomber has decloaked and is shooting you again, together with the 20 other bombers.
Bomber fleets would be very oppressing.
Bomber fights are already very one-sided, they don’t need a massive buff like this.
