I don’t love free wargear (because there will inevitably better or worse options when everything is a straight swap whereas with points cost you can balance finely), but I can see that it makes life easier.
Fixed unit sizes, however, are supremely shit. All in all totally ripped the variety out of list building, which was one of my favourite things about the game. Lists now will look mostly identical.
It is simpler. Instead of having to decide between an AP5 weapon or an AP2 weapon that’s more expensive but otherwise identical, now you just take the AP2 weapon because it’s objectively better than the AP5 weapon.
In this case simpler is not better.
