So I've been playing somewhat casually on Live for a few months now and the game has changed a lot, but it's similar enough that it's enjoyable. In some ways, it's worse than expected, but in a lot of ways, it's much better. I've gotten far enough along in the expansions where the evolution of the game has really started to become noticeable.
I'm 115 now and things are starting to feel a little more 'dangerous.' Named creatures aren't like the old days where they basically just hit harder and had more hp. Some of them have boss-like mechanics that you can't ignore (unless you're way over-leveled/geared) or you'll die.
I'm not sure that I like having so many new abilities. It feels a bit like EQ2 where I just want to put them all in one macro and spam that button even if it's terribly inefficient. I can't really bring myself to do that and I'm sure it'll get easier as I get more familiar, but I still hate needing to have a massive number of keybinds. I know a lot of people mouse-click their abilities, but those people are troglodyte heathens.
I haven't grouped with anyone yet and I probably won't for awhile unless I absolutely have to. I'm not avoiding it because of them; I'm avoiding it because I don't feel proficient enough at the game just yet.
