Remember guys, hardcore can never fail, hardcore can only be failed. If this game turned out to be a disaster, then clearly long attunements and exclusive raids aren't really hardcore after all. Never mind that every hardcore on these forums had been screaming for exactly those things for years.
Reality check: This was it. It's over. Everyone is pretty much done trying to clone WoW, much less trying to clone Vanilla WoW. There will never be a successful "hardcore MMO" as people here understand the term. The future is a slowly declining WoW with it's LFR and casual bullshit staying on top forever, until the genre finally dies off or is reinvigorated with sandbox games that don't particularly resemble anything we have now.
