I skimmed through the paper and one possible problem is when actors communicate with each others it might create a lot of network traffic, especially if one node goes down, it has to sync and might create a load loop as the load of the other nodes increases. A better way is to let the client do the orchestrating of talking to different nodes, so that no server-to-server communication is needed.
