I tried the pact with my wife and we made fresh brand new characters and started together. We did everything till lvl 3 then she logged out to play the sims. I continued and went on a sewers team and everyone else hit lvl 6 and I was still lvl 3. I asked around and they said it was broke so I undid the pact and later found out that you get the xp when you zone. So far that is the only thing that I heard about whats wrong with it.
