I for one am not bothered by the "lack of content" simply because I (me specifically) have a ton of content to still do.
I never tried solo deep dungeons, so that's been fun. I've been working on my Pteranodon mount also and Mentor Roulette. Plus Cosmic Exploration which are kind of all a grind.
I haven't even done all the EX fights/Savages etc. So getting to do that finally.
