I pick smallest needed value type, and some values encode multiple fields (i.e. type/state/frame are all in uint8). Node.js uses cast to unsigned 32-bit integers for bitwise operations on numbers, so bundling doesn't pay out as much in CPU as does in bandwidth savings.
2TB of data is really not that much. Say you run at 30fps, streaming only 2D position (say, 2 x uint32) of 100 entities to 200 clients...
You bring some sanity to that with less frames, less entities, naive delta not sending updates for entities, etc. It's really not surprisingly big number.
I'll definitely explore world state deltas in next game, but this works good enough for now.

(64 * 100 * 200 * 30 * 60 * 60 * 24 * 30 ) / 8 / 1024^4 ~= 11TB per month.
