Definitely not a fan of fixed unit sizes.
Free wargear I'm a bit more undecided on. I like just getting to kit to the teeth, and using options that usually are rarely worth the point cost. I also like that it is just simpler/quicker... Buuut, as tyere will be objectively better options that will always get picked and I don't like not being able to just remove some equipment to fit a point limit and instead have to change whole units. The building blocks become much bigger, meaning list composition ends up more rigid which I don't quite like.
