Is it true that players will no longer be saved to heroics? Does this mean players can chain farm heroics for Champion's Seals?
The Heroic lockouts still exist, however the difference is that the random heroic option will ignore any potential lockouts a player might have. This means that even if you run every single WotLK heroic dungeon in a day, you can still choose the random heroic option to continue running WotLK heroics that day. As mentioned above though, the heroic dungeons you have run the most that day will be the least likely to be randomly selected for your continued play by the dungeon finder system.
it's not 100% sure how the dungeon finder works. But it cost nothing trying auto extend every day. personally I have nothing against oculus but I dont like this dungeon just because peoples always leave in the first 20sec.. It make me rage to wait another 10 min for a tank/healer.
