There is something wrong with new raiders nowadays. They are not being taught to try their hardest and perform to their maximum capabilities. Because Blizzard made Cata and WotLK easy mode for raiders like you, now a lot of the raiders are just terrible players who can barely go 2/12 in ToT, let alone clear any heroic modes. When I joined this game back in TBC, I always thought to myself how if I kept pushing myself to my limits on my character I can go raid BT and other high end raids. In TBC, all I ended up clearing was Karazhan. In WotLK, I cleared a lot of the content, including 4/5 H ToGC on 25m, and 11/12 H ICC 25m. And wanna know why? Because back when I joined, there wasn't any of this LF-whatever BS that plagues the community. If you wanted to get anywhere, you had to work for it. But now Blizzard shot themselves in the foot by targeting the casual demographic, because it causes new players to stay bad, and encourages people not to learn from their mistakes if they're gonna get their shiny pixels at the end of the day no matter how terrible they are.
