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.
If that’s the case chainswords +1 attack on 5 guys isn’t going to be the difference that matters.
Your point about chainswords is valid, my point was more that the idea of a power fist and melta were the “objectively better choice” isn’t correct. Against hordes I feel a power weapon and a hand flamer would be better.
As an aside, how do you have your models kitted right now?
