Something most annoying I found, and likely others have found before me:
Pets - be they bots or MP demons/meatballs - are affected by the level limits. For instance, if your pet is level 200, and you are a level 125 MP - if you're attacked by a level 125 agent, your pet will refuse to help you out. Only if your opponent is in acceptable level-range of your pet will it attack.
A bug - another bug, rather - which must be fixed.
