Well what would you want- them to put 10% of their development time into creating raids that only 1% or less of the community will do? I see a lot of raiders complaining that they aren't getting more development time, and then being mad that players who like other types of content aren't happily saying 'yes SE, please do less for us and more for them'.
The sheer amount of cockiness as you look down on players that don't have time or the skill or the organized group to do 1% challenge content is likely a big part of why, for the last decade plus that I've played MMOs at least- there's always this division.
But no, there is nothing wrong with hardcores and raiders wanting more content- there's absolutely nothing wrong with that. But, you also need to realize there is nothing wrong with casual players wanting more or at least the same level of content- and casual players aren't stupid, despite how raiders tend to treat them, they realize that development resources are limited and if something gets more attention, something else gets less attention. Most casuals have played enough MMOs by now to fully realize that.
So again- there's nothing wrong with you asking for more of something you like, but stop with the pity party when other players say they want resources to go to something they like more than raids.
