Basically, as of the expansion release, the only part of the game that's still decent is raids.

I disagree fully. The new maps are fun and absolutely stunningly beautiful. They require groups to defeat and the united effort of several commanders to accomplish. They progressively get more difficult and have OODLES of things to find and discover and admire.

sPvP is insanely broken, WvW is insanely broken, all of the fun stuff that casual people used to do has been utterly nerfed beyond recognition, dungeon rewards are non-existent, fractals is a joke...

Entirely blown out of proportion in every account and has 0 basis in my experience.

Most of the new expansion content is a joke. The story is half assed, the new maps just spam the same event chain non-stop, rewards are incredibly unbalanced, everything is super grindy

Again, no basis in reality at all. I enjoyed the story, the very, very end was a little heavy on the cheese but I liked it. The new event maps can actually fail. But they repeat as in every time you do Molten Core it repeats too. What a thing to say. Rewards increase the whole ride. There is NO need to grind at all. Just play the game and things come. People who want first everything have to work that much harder to get it instantly, which if you think about those types don't really hate it at all.

tldr; Anet pretty much ruined GW2 for their old players and the new players that are drawn in are going to go 'lolwut' and leave.

I would really like to know what this is based on. So far everything has at least the smallest trace in something perhaps true, but this? I literally can't even...

And they have a very set schedule to Gem Store releases. In a game with Micro transactions.

TLDR; You're complaining about things that don't exist and/or thoroughly misrepresented.
