For engineer, for like some gears he has, make it so that he can deploy drones. Obviously make it like you need the highest level of engi for that or else it would be way too op. Only 1 drone too and probably like 75-80% of their health since you can farm XP easily if its 1 shot and a lot of people are stacked on a point. But it would be a cool feature for like the new rush map since it looks more modern, middle east vibe where a lot of drones were used.
