Yes i do. With mmos coming to mass market casual gamers with next gen consoles blizzard is going make massive changes to wow over the next few years. And those massive changes are going to see them push more and more casual content to keep people playing wow. They are going to stop altogether making ANYTHING for hardcore gamers and put 100% of there effort in casual content. Within the next few years heroic content will be done by less then 0.5% of the player base so they will stop even putting the time into balancing heroic raids. They also know even if they got rid of heroic content of those very very few people that do them 90% will still stick around and do the casual stuff.
Over the next few years mmos are going to see there biggest changes they have ever seen all because the mass market of console gamers will be able to get there hands on mmos. Hell even blizzard has started those changes. They scraped Titan to start it again so it can be release on consoles and pcs. Blizzard knows where they money is at and it sure as hell isn't with hardcore gamers.
