I don't agree with dismissing complaints, but there are issues then there are issues.
1.0 was broken, 2.0 has some things that could use some work.
Currently there are people that think an issue is a lot larger than it is in 2.0. In 1.0 there were WAY too many white knights. Basically things have reversed.

Durning the initial release I gave 1.0 the benefit of the doubt and made some excuses for it. I assumed SE would fix things from beta to release and had my blinders on. Though , slowly I found that the game was horrible and virtually unplayable; it was the antithesis of "fun." I tempered my complaints, that I did have, and left for a while (played XI) before I was rated down into oblivion.
If you were around the forum at that time it was very, very polarized. Ultimately the white knights and fans that stuck with it, had ZAM to call home, and rightly so. 1.0 got better, though I didn't give it a chance because, well, I'd been burned by XIII and 1.0, so I decided to bow out.

Now 2.0, along with Yoshi's ever present communication, is a complete reversal. It's fun, responsive, solid and immersive. As a beta it is more polished than most games. (I remember falling off the boat in Southshore (in WoW) at release, getting stuck and having to ask CS to release me, and rollbacks were a common occurance...anyone who played WoW in the beginning knows how many days we got credited to out account.)
There are things that I'd like 2.0 to have and things that probably should be in game, but that's a lot different than saying the game is broken.
A lot of complaints currently are either subjective or small objective complaints that should be addressed but are being overblown by a small group of people.
