This is the nature of early access development, maybe this is not a priority on their list for now. You sound overwhelming negative in almost every post you make, maybe you should just wait until the game is fully released before reaching an unsubstantiated conclusion.LOL you obviously haven't been following the recent conversation in the forums.
We've been waiting over a year and siege AI + armor still hasn't been fixed. The running joke is that all we've got is sheep textures and a barber and that's about it.
It's not that the game hasn't progressed enough. It's that it hasn't progressed and there's no evidence that it will progress much further. Devs have been actively telling us that many of the features most players want are not even in their minds. Glaring issues present from EA Release haven't even been discussed by devs.
