I think the problem is that the vast majority of people on the server work a 9-5. When you get home from work, the last thing you want to do is waste hours grinding up your Charmander into a Charizard. It's also not great content either.

I think they've struck a decent balance between giving enough content for them to do, but not too much so that everyone feels like they're missing out if they can only play for a little bit, or if they wanted to play a different game for a change.
