Maybe you guys need to approach it a bit more casually and without expectations.
I was called a troll here a few pages ago, but I think my approach to the game is valid. There is no end game after lvl 70.
I accepted that and am just playing because the game is fun until I hit the wall and need to do something to progress further, like needing to get to T3 no later than lvl 45. I think optimal level to get to T3 isn't 50+, but lvl 42 because that's when lowest lvl items drop in T3.
And I just treat lvl 70 as a final level and then either take a break or make an alt. I play about 1-3 hours per day, spread through the day (about an hour, max two per session).
I'm sorry but no. A "casual approach" isn't going to fix the fundamental issues with balancing, pacing, poor dungeon design, character progression and grind. The game needs to mature. It simply isn't satisfying or fun in its current state.
