To be fair after TTK they are trying to focus on casual.That doesn't sound like an improvement to me, what's the point in playing if the main stuff is skip-able and getting to max level is super quick... what is there to do except PvP?
Destiny 2 is basically the Destiny made for casual... little to no grind, max level fast without never do end of game content, no reason to play Raids, Nightfall, etc.
