Theres a few factors people dont get about why they think its lazy training.

People might want to consider things like POTD for the rise in 'lazy play'. POTD and speed lvling means players arent learning their classes in an in depth manner. And you dont need to know your class all that well to clear POTD and the like.

The problem MMOs always face with more and more content is that to allow new players to 'catch up', they end up dumbing down the content that would teach players how to play their class effectively, or even the game at large.

To many people get to max level way to quick, then try to do end game content just like how they did the power lvling, and well, we know how that turns out. If you want less Lazy play, lower lvl content needs to be not so easily bypassed. No POTD for sub 60 alternate classes. No unsynched runs for sub lvl 60 characters. Etc. Force people to play the content.
