I think Crypto is very strong when used well in a good squad. Season 3 does place more emphasis on squads which is a good thing. His drone is really well designed in terms of its capabilities which means there's plenty of things to learn and keep you interested in Crypto.
Is the EMP too big? Probably. It would still be useful to squads (if it were nerfed) but would also go some way to not making already good squads too strong. This opening phase of Season 3 has been characterised by very powerful Charge Rifles and EMPs. I'm pretty sure players are ready for some nerfs by now.
