Crypto is one of the most under-used legends in this game and he needs serious buff.
While I think he has a decent kit, it is only usable in very seldom circumstances and anytime besides that he has no abilities to offer to the match.
I think just adding an option to - when his drone is out - let him decide if he wants to call back the drone or let the drone just hover in the air and it gives the position of all the enemies in the vicinity on Crypto's mini-map until it is shot down or called back while Crypto can be fighting.
The area it can cover to track positions should depend on the height of the drone's position so it can't be abused indoors.
