So let me start this off by taking us back to D2. You start in Tristam, you work your way into the Cathedral, fighting off various bosses like the Butcher etc, and end up at the end of the Act fighting off Andarial herself, a lesser prime evil.
Act 2. You hop on a caravan to go east to Caldeum. There you fight big bad bugs, Lacuni, sorcerers, and finally Duriel…another lesser Prime Evil.
Act 3. You SAIL east…remember this… to go to Kurast. From there you fight a bunch of little shts, little shts stacked on little sh*ts and sorcerers, bugs, and finally Mephisto himself (the Prime Evil of Hatred).
Act 4. You teleport into the heavens where you fight all kinds of things, including angels and finally Diablo himself, the Prime Evil Lord of Terror.
This was all in one game, one purchase, the game is still going strong all this time later because the progression of the game is extremely good, you feel your character rising up the ranks. Now we can skip over d3 as I dont think its really relevant here (the devs said they wanted a more D2 feel to this gamem even tho its progression is quite similar to what we got in 2) and go to D4.
To keep this post from being TOO long (i know too late im sure), and you get a weird kinda back and forth progression to the original game where you fight Lesser Prime evils, then just dudes hopped up on some Mommy Lillath juice, then some rando church people, then back to a lesser prime evil, then back to some more powerful humans, then mommy herself. Weird progression but okay.
Now this expansion. “Chase down ney” only to be stabbed in the back by a burny boi, while we stare at Ney. Then they apparenly let her go (why?) and then we get saved by someone, we run all over the place trying to help Ney get loose of the stone, go into the spirit realm, fight some dude we never really heard of before this, then we go back and fight the burny boi, then we fight a “splinter of Mephisto” and we get betrayed.
This expansion should have culminated with us fighting Mephisto, only for him to have released his brothers (as we heard him say he was going to do) and then the reprecussions of that could have been dealt with in the next expansion. 60 friggin dollars to have half a story is not okay. Instead we paid all this money for an intermission story. Pretty lame imo, Careful blizzard your activision is showing.
Edit: Oh yea, and the sailing east, why? I had no idea it was literally just like, over the river over there, and if you want, you could like take the bridge. Its about 5 minutes give or take from Caldeum to Kurast via horse, if you sprint. It just breaks the image of a vast and unique world when its all kind of just…well right there. So where was Ney going in the boat in the last one, why was she in a boat at the start of this one? Why didnt we follow in a boat?
