People who played WoW, and comment on end game, likely weren't around at release.
I'll repeat facts I mentioned before. First 3 months of WoW were endless UBRS to get "keyed" to Molten Core.
Then, 9 months, 9 months, of one, single, end game raid.
BWL was not released until after the summer.
When an MMO is new, everyone starts at 1. Low level content, for the ONLY time, is crucial and important.
After time, when the masses of customers are L50, their focus will change, and endgame content updates will become the focus, and leveling content will be less of the focus.
This is standard. This makes sense. This is exactly how that other MMO's proceeded.
Focus on leveling content, make a mandatory end game raid, and focus more and more on endgame over time, once people can use it.
Working as intended.
