I've done every major instance, and pretty much every mission i could lay my hands on. I end-gamed and i haven't even hit level 40 yet (34 to be exact, using my Gageteer/Munitions). I've soloed about 9/10 of the game, cosmics and major instances being the exception.
Am I to wait for the next patch for the new content? Why? Another week of mission soloing and a instance later and I'll be waiting another few months for the next release. I can't preoccupy myself with PVP, its so unbalanced there's virtually no point. I could sit around and attempt to unlock everything in my achievements book... but i just have flashbacks to War Online and shutter at the thought that the only person i'm going to impress with something like that is myself.
I guess to say, for me at least, is that i was looking for something a bit more challanging. It wasn't, and the in game content is pretty slim and extremely repetative. Nothing is really holding me to the ropes on deciding this one, unfortunately.
The only thing i found that peaked my interest as of late 'was' mortal online. After downloading the beta, and then reading a post by one of the developers, he went on to say don't have high hopes for the game for at least the first year after it is released. All your going to get is basic content and nothing more. At least he was honest, but 'basic' looked like crap, it felt like crap, and i'm sure if it had a smell through my monitor... it'd smell like it too.
