Tigole announced two drastic changes that will be made in Patch 1.11 for the Public Test Realms:
Tigole: “We’re going to be making two new upcoming changes to instances in Patch 1.11:
—First, by popular demand, we’ll be removing the release timer in instances. This includes dungeons, battlegrounds and raid instances.
—Second, we’re going to have to institute an anti-exploit measure on certain encounters. Certain encounters (almost entirely raid bosses) will prevent people from zoning into the instance while that encounter is engaged. If you attempt to zone into the instance while that encounter is engaged, you will be resurrected at the entrance (outside). We will be making adjustments to the entrances to Molten Core and Blackwing Lair to compensate for this. Combat resurrections, soulstones, reincarnate etc. will still work fine. This is primarily to combat graveyard rushing in instances. Again, this will only be on a few select encounters, almost entirely limited to raid bosses.
—We’re looking into setting up a server of copied characters seperate from the premades. This would make getting organized raids going much easier. No promises… we’re investigating right now.
—We’ll be patching the PTR soon. We’ll try to put a durability repair NPC in the dungeon (for free) to facilitate testing.
—We’re aware of the ghost portals and fixing those for the next PTR push
—We’re aware of the instant arcane explosion assertion and we’re fixing those for the next PTR push
—We’re putting the dungeon on a 1 day reset for a few days to help expedite testing of the front bosses/areas. We’re planning on adding time to the reset in a few days/weeks once we have gotten enough testing on the front content (it will be hard to make too much progress with the dungeon constantly resetting).”
