Clean Play document - John had this idea that if you set community standards so that everyone always played by the letter of the rules with the strictest interpretation and no forgiveness of errors then people would not assume other people were jerks for playing like that (as happened at the WTC in some games). This is among the dumbest sentiments I have ever heard expressed out loud (particularly if you include that he doesn't want it at most tournaments but still wants it to become a community standard that everyone is used to). Thankfully there were more than a few people who argued that maybe you should just talk to your opponent so you are both on the same page with that stuff. I hope this doesn't get made.
Legion and the evolving meta - I feel like the meta is evolving away from Saeryn at the moment. Actually I feel like it's been happening for years but she was so strong it has taken until now for me to start thinking that its time to take her out of my tournament roster. Years ago I felt like I could drop her in almost any match up and now she seems to be standing on rapidly shrinking grounds. The new Skorne bugs are going to put that match up out of her reach and warders have made trolls a difficult proposition for her. I have been already moving in the direction of Vayl1 and Thagrosh1 as a replacement but the WTC guys have been talking about Thagrosh2 and he is another contender for that spot. I also think it might be time to have another look at Kallus.
8 wound infantry - are currently big in the meta and the sacral vault I think is going to improve them again when it comes out. I think as a player you need to be ahead of the curve, find ways of killing multi wound infantry in a way that puts you ahead. Press Gang are great for this because they are so cheap. MOM-Miami were talking about this and I think they missed the main points. You get 20 for 12 points which is 6-8 multiwound guys, they have tough and fearless, Hawk is hard to snipe out because she has sucker. It's almost impossible to trade favourably with multi wound infantry against them. Other things I made a change to my Harbinger list and now I have a unit of Hammer dwarves with attendant priest precisely for these kinds of lists, they replaced the battle engine and mechanic as with the reduction of single wound infantry the battle engine is losing stock. However I don't predict this to be a sustained trend. One of the reasons Fist of Halaak is so popular is because Skorne had problem match ups it helped with, the bugs change that equation. Warders are really good but they compete with runes of war for list space and are solved by a lot of the same lists. Morv2 lists are moving away from my favoured style of multi wound spam, I know I was thinking about trading out a multi wound unit for blood trackers and it is a change a lot of people have made.
Exigence - I think there are only two dead releases in the book, the legion beast pack and the circle character heavy. The skorne beast pack still aren't great but there are interesting things you can do with them thanks to snacking and their animus and Skorne beast support. Skorne and Circle picked up game changing models in the circle lessers and the Skorne bug heavies. Trolls and Legion I think got more of the same but it was really good. I'm currently the most excited for Jaga Jaga.
Spell Draft - I really like this format. I like the drafting process and the way you play your list changes so much with the spells you get. If there is a downside it's that it is really easy to forget a key spell your opponent has and get assassinated. I might even suggest building a list for that purpose.
