I am not even sure this was in the 2.1 patch notes. The threshold for allied with the Federation, Alliance and Empire are now at 90%, up from previously 80%. This triples the amount of effort to get back to allied from reputation decay (for example after a while out of the bubble exploring) and gives you a much smaller buffer above the threshold to keep your allied status. It also negates FD's own statements that decay would happen only to "slightly below allied". If the 90% threshold is there to stay, why not increase the reputation decay end point to 85% accordingly?
