How to release raid content for both casual and hard core players every patch.

[Zumocano]

I like how people are using the term 'hardcore' and 'casual.' They aren't correct. The terms you're looking for are 'good players' and 'bad players.'

Incorrect. "Hardcore" and "casual" players are determined by how much time they invest into the game as a player. Casual players are typically those who have a life outside of whatever MMO game launched this month, or they just don't want to play a game like a full time job.

It's far enough into the game that anyone who can't down BC is bad.

I agree that anyone that cannot pass HM Titan at this point who is geared for it is a terrible terrible player and should probably stop. However, you don't see SE nerfing Titan to let scrubs through. What you see them doing is introducing new content to allow them to gear up to the point where a group can have 1 or 2 people die and still defeat him handily.
