I think everyone missed the OP's point. Most people look at the system and say every other patch one group (hardcore or casual) get something. But the truth is that every patch the casuals get something as at each hardcore group patch the previous hardcore set gets the "echo" buff making it accessible to the casuals. On the casual patches, the hardcore get something to experience a few times, but nothing new to challenge them.

While the hardcore group is only about 10 or 20% (prob less actually) of the community, I can see why they dont cater to them for every patch, and it may take longer for them to actually make content that will truly challenge us, and this is why we get only every other patch, but i guess only time will tell
