You do understand how DLC/expansions with level cap changes work, right? Do you think that after Wrath of the Lich King came out that you would see people in Shattrath who weren't leveling? No way. Get used to it, it's not likely to ever change when a game is designed to accept updates like that. It's just the natural progression. There will always be nostalgia for old content when you had "the most fun".
