I saw one post on the AoC Vault about it....the guy claims that /follow is in the game and "works" - he said that it is fine but you just happen to get stuck evereywhere...on various objects...each top step of stairs etc.

Assist is in as well...he was waiting for his special gaming keyboards though and didnt use his other characters as one ought to...they were kind of bots but I guess with the right key duplication software it should be fine...
