The issue nobody wants to address

Yes they are in the position to nudge the community, but what's it gonna cost them? Sadly SE have to cater to the majority, which is greatly holding the game back from what it could really be.

Indeed they do, but at the same time, if they can't continue to keep people interested. ie, they are bored because everything is the same. But at the same time, they do also seem to have a bit of integrity with their product, look at MSQ gate to HW for example. They aren't simply in it to make the most possible money, they want to make the most possible money with the product they want to sell. So, one can hope.
But in the end, they are the only ones in the position to make the change. Do I think they would have to do it gradually over a few expacs, yes. Not saying they could just start introducing all mechanics heavy content in 3.1. They would essentially have to groom the player base. But then, isn't content supposed to get more challenging the further you get into a game?

I think the over reliance on dps checks is bad for the genre in the long run, but don't know that it will, or can, change.
