Yes, I realize I'm just another asshole who plays wow, and I'm not an authority on the game, but I have done most of the quests for the new followers, and would like to share my thoughts. So, if you haven't done them and want to be surprised don't read any further.
In order of how I completed them:
1. Shaman - Magatha Grimtotem?!! Are you fucking serious?! The tauren who is the reason Cairne is dead, and Garrosh is still alive dares to enter the Maelstrom, and I didn't just get to annihilate her? The quest part was good, especially when we ultimately deny Magatha the Doomstone in the end. I am not a big Thrall fan, but I would have rather had him or Aggra, honestly. I have her currently deactivated.
2. Mage - Aethas Sunreaver!!! I was happy to see him as part of my Class hall. The quest was very focused around Aethas trying to keep himself under the good graces of the Kirin Tor after a sunreaver stole from them, and I think it is good to see his character be redeemed. Currently a follower.
3. Warlock - Kanrethod Ebonlocke. The big green demon at the end of the green fire quest now joins the warlocks. From a story standpoint, this is a form of redemption story that I like to see, and it also does a great job of binding the story together. Jubeka was charged with keeping Kanrethod banished, and it was not explained why she was at the class hall in the beginning, but this quest line ties that up. Currently a follower.
4. Paladin - Nerus Moonfang. The Moonfangs are starting to grow on me. I am glad the story writers have tried to flesh out the character of Delas Moonfang, and I would not be surprised to see night elves become paladins in the next expac, and Delas Moonfang being its precursor. The quest was on point, made sense, and seems to be pushing the bounds of character development, which is good if you want to see a fantasy class game unfurl in a believable way. Nerus is a distant uncle of Delas', and as a ghost has joined the paladin ranks as well. Even cursed beings are not beyond redemption. Illidan is a case in point, so why not Nerus, as well? Currently a follower.
5. Warrior - Darius Crowley. So, don't get me wrong, I have been a big fan of the Crowleys and have enjoyed working with Lorna Crowley in Stormheim, despite it not being one of my more liked zones. As one who quite enjoyed the Gilneas starting zone, as well, it is good to see Darius joining the ranks. His part in the quest line was too limited, and I thought it was going to go another way. While I am not displeased about the choice Blizzard went with, I figured we would be getting Danath Trollbane. Danath Trollbane left his post in Hellfire Peninsula to escort your warrior to the broken shore and got split up before you "died" but Odyn spared you from death so you could fight on. No one is quite sure what happened to Danath Trollbane afterward, but I think it would have been better if he was the one who became the follower. Currently using as a bodyguard.
6. Hunter - Nighthuntress Syrenne. It's interesting to turn a hostile into an ally. It doesn't appear she is a friend of the Nightborne, and joins you after you demonstrate similar goals. I'm glad this was who was selected, though I admit, I thought it was going to be Nathanos or Velanora. Currently a bodyguard.
7. Druid - Thisalee Crow. To be perfectly honest, I called this one. I assume the horde one is that tauren counterpart from WoD. I've always enjoyed Thisalee Crow, from all the way back in Cata. The dialogue she offers is reminiscent of that time period, too. currently a follower.
8. Death Knight - Minerva Ravensorrow. I don't know what to say, here. She's just the right amount of bitchy, and gets the job done. The quest line was awesome when it wasn't all buggy. The DK followers have been the subject of a lot of speculation, especially where the entry of the 4 horsemen were concerned, and whether or not we were going to see Thassarian and Koltira together in action, again, so, I guess they get a pass here. Maybe they will try to make her a good strong character... who knows. Currently a follower.
Still in the process of the other 3. So, what kind of criticism would YOU offer blizz? Did they hit the nail on the head? Did they miss the mark? It's difficult to say definitively but, go ahead and discuss. Have a good day.
