As a Kharadron Overlords player, this rules is AWESOME. yes, all my untis are ranged units, but I asked for this since first edition and I'm glad to see it.
It hits right between strategy, fluff and of course, the fun of playing AoS. And that's exactly what I want.
I'm 100% with this. A los of space between units means a lot more opportunities to make plays. Grouped up units is fine even if it will be hard in the first games.
I still miss something that promotes charging, even if your unit doesn't have a weapon with the charge USR.
