My biggest issue with GRPC is direct mapping of ip addresses in the config or at runtime. From the docs: "When sending a gRPC request, the client must determine the IP address of the service name." https://grpc.io/docs/guides/custom-name-resolution/

My preferred approach would be to map my client to a "topic" and then any number of servers can subscribe to the topic. Completely decoupled, scaling up is much easier.

My second biggest issue is proto file versioning.

I'm using NATS for cross-service comms and its great. just wish it had a low-level serialization mechanism for more efficient transfer like grpc.
