Yeah, that sure is a bug that has been around for so long... That it will probably stays forever...
What are these long broken class features you are talking of ? Most of them are a few days old...
What I like is having new content, new features around. Most of your recrimination are based on nothing. Of course, in the few days after the release of new content there will be new bugs and quite quickly the most important will be fixed and some time after most of the rest will be too. Of course there are glitches who never get corrected, but every program (at least every major one) has some.
Dunno, I never bother, most "bugs" are unsignificant.
This shows us that you definitly have no idea what computer programming is. While some bugs are mainly a few things to fix such as programming typos, some which seem so simple to the user would requier to rewrite a large portion of the code. So, yes some can be corrected in matters of minutes, but not all...
