So after the guardian nerf/buff, she feels just weird, and even underpowered (hold up).
Now her revive buff, was needed. She has no healing abilities so she just felt useless when it came to dishing out revive health.
But her shield…
Now its more reason to use it as a reaction, as the shorter lifetime and cooldown, however they never changed her deploy time. It NEEDS to be reduced so it can be used more skill based, less shield based. She now can only stop airstrikes, and the enemy team has to be EXTRA stupid to waste their ability on her.
If we reduce her deploy time by at least 40% she would be somewhere, where if she is played right she is a beast
summary - The drone is being forced into more reaction gameplay instead of shield gameplay, but the still long deploy time (incapable of reaction stopping arty strikes, javelin rockets, etc) doesnt support that. So ye, decrease the deploy time
