I don't understand these generalizations... Why can't the developers decide who they want to appeal to? Don't indie games exist because they fit in a particular niche? They don't have to appeal to everyone (nearly every game design document I've read even has a "target audience" under it) - they can appeal to the casuals, the hardcore, or both if they so choose. Technically speaking, they don't have to appeal to anyone. Not a great financial investment, but it's their choice; they're the developers.

I think the issue is that there's variety. Back in, say, 2005, there were a lot less options for popular MMOs than there are today. I mean, a couple that I could name from back then are FFXI, RuneScape, Guild Wars (just released in 2005), and WoW. Ask me to list MMOs from 2013, and I can say RIFT, WoW, FFXIV: ARR, Guild Wars 2, Neverwinter, Vindictus, The Secret World, SW:tOR, EVE Online, Tera, RuneScape, and a ton more... Point is, the MMO community isn't just condensed to a few options; there's a bunch of games for us to choose from and enjoy. This should be celebrated! But instead all I happen to see on all the forums for these games is "this game is dead", "this design will never work", "everyone's dumb but me", and so on.

My point is, find the MMO you enjoy and enjoy it. It's critical to provide feedback, but it doesn't help anyone to run around claiming the game will be a ghost town in a month. Stop being so hostile to your fellow players and enjoy the game. A strong community has the power to carry any MMO, no matter how "bad" it is. So kick back, relax, and smile. If you wanted to stress out, I'm confident you know of many better ways than videogames to accomplish just that.
