neutral about this
CI and GOC are definitely not over buffed, as they are already competent GOI's and dont need any extra help.
Heck, check when the last GOC/CI Specific buff was that is Combat Related. Could take you awhile for them
As for over nerfed, the closest to relevant thing right now would be that SSL recently removed the CI COM and LTCOM, and removed the GOC GEN (With the LTGEN following suite), as they felt it was Necessary
Not a direct buff, but at the time Affected the GOI's badly, until they Adapted. Other than that no other Nerfs to the GOI's directly have Happened (Excluding Buffs/Nerfs that directly counter CI, such as the Hacking notifications for E11 and The changing of certain Chemicals)
Just a wee rant i wanted to go on
