The thing that I do t like about the AH is logging in and seeing 1500 of the same exact legendary bow, makes these super rare items seem cheap and worthless (which they are forthr most part)
Well there's roughly a million players per region pumping stuff into the AH. Assuming 1m players and 1500 legendaries in the AH, that would leave them at a 0.15% drop rate. Seems rare enough.
Spend less time, surely? By using the ah, you're going to spend zero time in game gearing up. I guess that could be a positive, by removing the need to farm/grind. But it definitely doesn't equate to spending more time playing the game.
You would need to trade anyway to progress in a relatively good speed. Parking yourself in a trade channel and pasting (using D2 example here) G:Runes W: IK would take far more time than simply checking the AH for a couple of minutes and going to slaying demons.
