This question makes you seem very young. I'm not calling you a child, but you are definitely on the lower side of the 1-60 scale.
I enjoy knowing what to expect, not logging in the next month to find all the things I've learned and gotten good at are no longer useful or relevant. I enjoy when these things are built upon and maybe made more complex but if they just give me different situations to apply these skills I'm happy as well.
Past a certain point in my life I became happy to find my favorite thing and put some time and energy into it when I had a break. New and exciting is good for what it is, but comfortable and familiar holds a lot of value for me.
I've changed significantly since I've passed my teens and 20's, but after that I became very sure of who I was and what I enjoyed. The time since this game released isn't a big chunk of my life.
also: if you are expecting 1.0 to 2.0 changes ever again, you will likely be disappointed. That was a huge gamble for SE which luckily paid off. Expecting them to expend that kind of money and effort on a successful project that's doing fine as far as the investors and company heads are concerned isn't logical.
