So it's going to be 90% the same game, but bases are changing on warmachines and big stuff I.e. cauldron of blood/ screaming bell. And characters can't join units........riiiiiiiiight.
It's either nonsense or characters can't join units and will just get sniped by magic and shooting, because the rules aren't really changing?
Makes perfect sense now they've explained it
On the assumption that the above is correct (which I rather doubt), I suspect that this would work out to where characters essentially don't exist as standalone units, and are more like the crew for warmachines. So you put their models next to the unit (like crew next to a warmachine), but they aren't *actually* there and simply get pushed out of the way if necessary.
Then, when it comes to combat, you add their profile to the number of attacks coming out of the unit as per normal. Attack allocation on a base-to-base basis is gone, and replaced with a more abstracted "up to X number of models can attack a character."
Why do it this way? Because I get the feeling that the character wall and challenge shenanigans are NOT what GW had in mind when they designed this game. I don't think they ever conceived of WoC characters with 3++ saves filling out the front rank of a unit of marauder horse or hounds, or brolock buses with 1+ save cav characters or skeleton unit full of cairn wraiths doing the same. I don't think they expected to see ogre gutstars with the characters sitting in the second rank, making way (or not) as they please, or running your black knights 3-wide so that the vampires / WK BSB can apply base-contact effects as is most advantageous.
Remove characters from the equation a la warmachine crew and you can simplify attack allocation through abstraction. No more counting how many guys are in base-contact. No more janky charges where you have 1 skeleton warrior fighting in a combat because that's how many guys you could close the door with. Easy Peasy.
Better for the game? I don't think so. If it lets you play a 2,500 point game in less than 3 bloody hours on average then that's sort of cool. But I really appreciate the complexity and nuance that exists in the game at present. I can see why abstracting out certain elements would appeal to a company trying to expand its player base, though.
WHFB as it presently exists is stupid complex, and full of all sorts of unnecessarily complicated rules and fringe cases.
