There's two things I'm not going to cover here. A) The new Farmers. Those guys need an article of their own. B) The new Hunters. Also need an article of their own, but it won't be as exciting as any other article ever.
So, Alchemists. Alchemists got Crucible.
Brewers got Pintpot.
Then there's my new favorite Captain, Brisket3.
The last two players to be mentioned here are Benediction and Grace. These two are extremely new, only coming out with the Book spoilers. There's no models in stores yet, but we've got the rules to at least start proxying.
Benediction is a tank. He's DEF3 ARM2, so he's going to get hit, but the 2 ARM help. However, his two character plays give him Sturdy to ignore the first KD, and the other gives him another 2 ARM against the next attack. This means that against most models, they're not going to get much more than a column or two against him in an attack, even on the charge, and because he's not KD, and has 2'' melee, he can counter attack back (for free once, with poised) and get a 1'' push minimum, maybe 2'' push. I wish the KD was a little lower, but oh well. Where I think this guy excels is hanging on to a ball. In almost all other regards, Harry the Hat is better. Harry has better TAC, better plays for control (Molotov and Goad), he has better access to pushes and damage, he does more for the team with his hat aura, and he has 2'' melee as well. Where I want to consider Benediction is just to hang onto the ball, little more. 2INF a turn maybe for his two plays, and he hangs out. I hope he works for the Brewers. He'll be a good option for Rage2 I think since Rage wants to kill the ball, and then kill people. With this guy, that gets easier. In most cases though, Harry covers more bases and is the better player.
So where does she fit in? I don't know. The thing about both of these players is that they're both Solthecians, so they'll give Mist a 2'' shadowlike dodge. That's worth something at least. Grace gives Mist 4'' extra movement, plus his 2'' extra from being in cover, which he should almost always be. Now Mist, who threats 10'' base (8'' sprint, 2'' melee) goes two 12'' with his cover bonus, and 16'' with quickfoot and shadowlike, both from Grace. In a Brisket3 list where Mist is the primary ball recovery guy, 16'' before dodges is nuts. However, that's really all Grace does, plus her healing which is nice, but everyone's been dealing without it for awhile. It's useful, but in a game with such high opportunity cost, it's expensive. Who do you take out? Gutter? Decimate? Not Mist, not Harry. Probably not Avarisse and Greede. So Gutter or Decimate, but Grace can't really kill people. She can, but it's pretty inefficiently. Grace only makes sense in pure striker games where she makes Mist absolutely ridiculous, or games where it's imperative that whoever is going gets there. Is your meta killing Rage2 and controlling him with AOEs and staying out of his threat range? Grace helps with that. She gives respectable threat to any beater in the Union, and she does it for basically the 1 INF she isn't donating into the pool like your other character would be. But then, that's all she does. She doesn't fight, and she doesn't strike, which in a Brisket3 list who at least wants 3/6'' for "I'm Open", it's something of an issue. She's better than Hemlock, but Hemlock doesn't play, so I don't know what that's worth. I'll buy her eventually, but I'm not going to stand in line for it. It's going to be one of those "I played at the game store, so I should support it with a 10$ purchase of some sort" things. That's why I have Crucible, Venin and Spigot2.
That's the overview. I'm not a tournament winning player, I just like to talk a lot. Strictly the Worst and Double Dodge both cover them if you want some tried and true experience talking. I think everything here is playable, and I'll probably play some Benediction IF he works for the Brewers since the Fish are raking them over the coals right now. We'll see.
Feel free to destroy my opinions with rational thought and logic. Hopefully it's an ok, all in one place overview. I may look at the Farmers, probably the Hunters as well (I own Hunters, maybe will own Farmers) and if I'm not absolutely destroyed for this article, I might let my ego type up a few more.
