I spent a few hours tromping around the Fizzcrank Airstrip (Which I apparently didn’t realize was there when I came through on the horde side,) and got to see the other side of the mechagnome infestation, which allows the player to actually cure the gnomes instead of just offing them.  This was a little more satisfactory than the horde side kill them all and let the gods sort them out approach.   Blizzard keeps improving the quality of their content. I think you get a lot of perspective on that by replaying through the level progression all at once, because there are definite points where the experience improves and the writing gets much better.  I expect that the next MMO or the next expansion will be incredibly written and well executed.
