From all thread that asking content (hardcore vs casual) : sum up objectiveto SE

[Silma]

This is the truth i've been rubbing at dev team face for like 3+ months...No game can please everyone...

the solution is different server !!!!!!!!

Please refrain from making such definitive statements. As pointed Amyrae, Yoshi-P already said there will be content for "both" type of players. You CAN have content that pleases everyone, just look at that MMO with 14M subscribers. And you CAN NOT have servers to seggregate people. That being said, as I pointed in another thread, difficult content is really what defines a game.

Hardcore dost not mean time sink.
There is no opposition between "casual" and "hardcore".

I think the best comment here so far is :

They need brainstorming.

They need manpower, several teams of developpers, time to think, create and test content. Ask the point of view of players about this or that idea. Post official polls on what content they want to be introduced next. Use their community which is the most precious treasure they have. Do not nerf content too fast.
