imo the quality of interaction with base suppliers is generally lower than any other type of encounter because base suppliers more often than not are grinding and not really having fun doing what they are doing, but rather thinking about the fun they are going to have once their base is upgraded or build modules and so on - so any form of interaction or slowdowns are a nuisance to them.
make them srp, lag is bad and quite a few bases and baseowners contribute with very little to justify for the base's existence as well as the lag.
