Over at the World of Warcraft forums, a Blizzard representative gave word that they have successfully changed how the infamous “Additional instances cannot be launched” error works.

The limit for instances per server has been notched up a bit, and the performance instances are being given are also improved.

The reason behind many players participating in Heroic instances is due to the recent 3.2 changes of Heroic dungeons providing Emblems of Conquest. This way, all fresh 80′s can get their Ulduar gear with just some grinding.

No word on when European and Australian servers will be seeing the fix.
