I look at games like WoW that had content for both casual players and hardcore gamers. Destiny is watered down to cater to the casual base and has nothing for hardcore gamers.

So if it doesn't meet your standards, try something else? I heard there is this cool game that came out yesterday. Try it out maybe. Be "hardcore" and expand your horizons.

There's no other game like Destiny though.

Which is as big as it is because of the majority. Ie casual player base. Without them, no revenue. Without revenue, no new content. No new content, no "hardcore" player base. And if the game is not fun for the majority (which would mean having some shred of success in a game), then again, they leave. Which ultimately makes it worse for the "hardcore" base.

WoW did it well.

Then play WoW. Because Destiny isn't that type of game so accept it.
