....ok, since you clearly didn't read any of that, I'll give you the shorter version (seriously, are you 8 years old?)
Grinding =/= difficult game
Wanting Destiny to have more content with less grinding does not mean I want an easier game nor is Destiny difficult AT ANY MOMENT
The most difficult content in the entire game is the raid and once you beat it once it's no longer difficult. The most challenging part of it becomes coordination other people.
