Good point, we do need more engaging content. I would love it if there were fun things to do like quests with interesting mechanics, especially group quests, even PvP will be offering EXP as a reward in 2.0. The problem is, they are adding all of this end game content like AF armor, dungeons, primals, NMs, etc and there is no fun and engaging content to do along the way (well, maybe besides Toto Rak...). They are faced with a decision, force players to endure through leveling methods they find to be a bore (grinding monsters/leves) or give them the option to bypass it so they can participate in all of this fun stuff.
I will admit that "afk leveling" is not a good system, but it's what they gave us. Until they give is something more desirable, its the only alternative we have. I think what the developers have in mind is, instead of taking away the only method of circumventing the grind, they are going to leave it in until the new systems are fully fleshed out in 2.0.
The simple fact is that in its current state, leveling is not a fun process for many people, and while I understand that some people may love grinding monsters, not everyone shares that sentiment. Just like some people aren't satisfied with end game, some people aren't satisfied with leveling. Both areas are lacking.
All I want are additional methods of leveling, once they deliver that, I could not care less about PLing.
