Q u o t e:
How can the ratings not get that high if numerous teams get to 2700+? Are there diminishing returns on the amount of rating you can gain off another team despite team ratings being similarly high?
It certainly is possible to get that high legitimately, although it would be unusual. There's about a 2% chance of seeing a 3000 rated team in a population size of 20,000 teams... about a 5% chance of seeing one in a population of 50,000 teams. So, with the number of battlegroups in existence it wouldn't be outside the realm of possibility to see a 3k team. Grats to them. =]
