Even IF they do that, it would take months to get to Naxx. Its not like people will be 60 in a week and have the gear ready at the end of the month. Take 1.12 as a basis and go with a cycle of opening like 2004-2006. Give all raids before naxx a 10% boost or whatever to balance the strengh of the new skills and such. Done. Is it that hard to understand?
