Yeah, if someone tells you this game is perfect you should take them on a camping trip or something. What I say is that this game will probably stick around with a healthy community (i.e. it won't implode after four months like every other MMORPG released recently).
It's more along the lines of, "This is the best MMO right now". If you like MMOs/RPGs, there's a good chance you'll love GW2; if you don't like MMOs/RPGs, you'll probably hate it. You should play with friends/other people, though, as solo play is less fun. While it's far from perfect (e.g., a number of upper-level quests and missions are/were buggy, and even some lower-level ones, too), the developers are pretty responsive, and there's a wide variety of things to do aside from the usual quest-like tasks:
- Exploring. The world is huge, the detail is incredible, and the devs have put all sorts of interesting places in out-of-the way locations.
- Crafting. You can spend a lot of time making stuff (as well as gathering the materials to make things).
- Jumping puzzles. I'm not a fan of jumping puzzles, but the devs have done some pretty amazing things if you like these. For example, in one area, there are some non-obvious things that you can do, largely involving some nasty jumping puzzles (nasty because there are monsters that try to stop you). If you succeed, you enable a special/secret boss event that everyone in the area can participate in (spoilers here).
However, the game does occasionally have issues, and the best way to see the current status is to follow GuildWars2 on twitter (or create a tweetdeck column with "from:GuildWars2").

Then don't commit crimes? Why would you need 50 of an obviously bugged TP item, unless your sole plan was to try to hold onto it and exploit it post-bug-fix at higher resale? For people who just were like "omg, bug! I want one!" and bought one or a couple for them and their friends, it sounds like that would have been completely overlooked. 50+ is a substantial amount of an item.
The "non-crime" use would be to salvage the items for rare materials, for creating better/rare weapons and armor. Keep in mind that the highest-level gear would probably take the resources of a large guild to create just a single set (side note for non-GW2 players: the "highest-level" gear is largely cosmetic. While they do supposedly have better specs, the specs are trivially better (+1%??), and don't really make a difference. People try to get this stuff largely for the bragging rights.)
