As you said I spend some time checking which armies I like or better could imagine buying.
Please let me share my views;
Kharadron Overlords: Spend some time on them, in the end, I've decided against them because everything looks the same and I'm missing variety. Seraphon: I like Dinos (who does not?) but I hate most of the old models and the book is to new. This may sound crazy but I don't want to have a new powerhouse. But mainly the old models scare me away. Disciples of Tzeentch: To be honest I like almost everything about them but definitely too strong - don't think they are really fun to play against them. Khorne: Looks like the book is well balanced - I just fear the power of the big Demons. You are right I could play without them, I love playing Aos because of the big centerpieces, so playing without these is like playing soccer without a ball for me. I know a lot of people say Khorne lists without these greater demons are stronger, but what I've learned from our games is, that people struggle to fight against 350+ point monsters like the undead dragons or Frostlord on Stonehorn. Nighthaunt: I love Death armies but these guys look all the same! No way! Orruk Warclans: Wow some cool models, especially the Megaboss on Maw-krusha but hey it's a little bit like FEC? Super strong dragonish Monster running around killing stuff? Ohh and my wife hates them.....
Please feel free to correct me if I'm wrong so far.
I think in the end I'll decide between Skaven and Gloomspite Gitz, but still, if someone is thinking I'm completely wrong with my thoughts about one of the other armies please let me know:
Skaven: I've found some nice and interesting models, I really like the idea of "Hey you want to do more damage, no problem but you maybe die!" They have some cool looking centerpieces and shooting. We do not have a real shooting army so far, so I would love to have one. But at the same time, I don't know if playing against a shooting army is a lot of fun for my opponent? Additionally, is Skaven really a "mid-tier" army? A big plus is that my wife would like to use some of the models for her Nurgle army as well.
Gloomspite Gitz: Hands down they look amazing! These squigs and trolls are AWESOME, I don't think they are a powerhouse by any mean. Could someone please confirm that an army of 1-2 Mangler Squigs, one of these big spiders and some trolls is still considered to be a casual list? I like the look of the army, I've read a lot of good stuff about the book - the only thing I'm missing is the shooting.
There is no discussion that the playstyle of the Skaven would fit me the best. I like magic - in a lot of other games, I like shooting so why not go for them? I have a bad feeling about the enjoyment of the person on the other side of the table....
