I think you could have come across better in your post had u been a bit more specific
I dont like farming. its the reason why i hate games like rift as that crap is all about farming and grinding and its boring.
Also, have u checked the new update patch? it contains some stuff on dungeons. dont know if that will help some of your queries?
Lol, I know, I just went on a bit of a rant and then couldn't stop

I have checked and it seems that it's helped some of the content, but Arah is now even worse because you can't farm shards from the bosses that are actually possible. There's a boss that's incredibly difficult, and my group just couldn't kill him, so I'll never get my dragon face

The trouble is WoW's end game is raid or die. The only thing I would want from that game is possibly the rep 'grinds' and even then the TBC expansion versions, not the weak LK/Cata versions.
What ANet should have done is launched with a few Orr's, so it isn't just Zhaitan you're fighting, have a few elder dragons on the go. Hopefully they will patch in that content on a regular basis, say a dragon/end zone every few months.
I don't think WoW was raid or die, you could raid but PvP was still good fun and you could spend time doing that to get rewards for outside of PvP. Whereas sPvP's rewards are cosmetic only, and the cosmetics are only for inside HoM, which I kinda don't like. But as soon as TBC came along with Arena there was almost 2 types of end games. I dunno, I hate WoW, I just wish someone else would pick up an Arena style system and give me something like that, and I admit that's 100% my problem and I shouldn't expect a game to be made exactly how I want xD
