Just to add to this, I don't think anyone is asking for a too fast progression through the game.
What's being asked for is a rebalance of rewards, a long-awaited culling of RNG and balancing more in favour of the player, and a more meaningful set of mechanics that allow people to grind without it being soul-destroying.
What's being asked for is an upping of the pace. Putting progression on top of the next Falcon Heavy isn't going to do anyone any good, or the game. Taking it to the mechanic and asking for a bit of a tweak here and there and a tune-up is perfectly fine, and much needed.
The player numbers tell all. People come flocking back when they can progress a little faster. I dare say people would come flocking back and stay if that was the case across the board.
