Thevedis and others alike are missing the one problem with your views on casuals. You aren't referring to the casuals that want easy content but the small group of individuals that might want said content. Wanting huge time sinks also does not make you hardcore. Both sides have a small niche that seems to want something that isn't worth the Dev teams focus to bring this game into prosperity.
Hardcore(the niche group) wants major time sinks on almost everything so THEY can have fun.
Casual (niche group) wants easy mode [I WIN BUTTON] content.
Both sides have stronger supporters that want challenging and engaging content. Not huge time sinks or easy mode buttons since those are not the paths that create an engaging experience for the majority. Modern MMOs should not use huge time sinks or easy content to attract people. Attracting to the majority is rather simple since the grey area is very common for True Hardcore AND Casual gamers. Not just people that are lazy or have the ability to play 22hrs a day.
