I'm really hoping this stuff isn't a hoax.
If you're complaining that a couple of tables make it too complex, you really should go and play snakes and ladders.
Having a 'normal' and 'advanced' game is the only way forward for 40k. Half the players want something with all the strategy of snakes and ladders and the complexity of rock, paper, scissors. The other half want something where you have to think a bit and actually get to make meaningful decisions in the game.
You can't keep both camps happy, so have two different rulesets for them. This is about the only intelligent thing I can think of GW doing in recent memory. In fact... it's just too smart for them, thus unfortunately probably a hoax.
Pre-measuring is great. It takes the game from being gimmicky and luck based toward actually having meaningful strategy. It's no longer about "guess which unit I'm in range to charge" and rather "which unit is more tactically advantageous to charge." Yes, strategy people, it's not a dirty word.
The only thing I really wish they'd change is to add some meaning to positioning in melee combat. There is no strategy during melee currently. It still runs on autopilot. Using something like Epic's assault rules where positioning actually means something would be good. The forced pile-in move basically negates any form of control or tactics on the player's part.
Although right now, any improvement is good. For those of us with even half a brain, the game is currently a tedious dice-fest that runs entirely on autopilot with almost no meaningful decisions for the player during the game.
