Alex normal has been stated as harder than CT. Yes, more will prbably get through it, but there will be some incapable of improving and will be stuck trying to get through it. Not to mention the more complex rotations players will need to learn to pass the content when there are still players who cant even figure out the simpler rotations we have now.
It wont be 24 person content so some bad players won't be able to be carried as easily as what happens in all the versions of CT.
Alex normal is aimed at mid tier difficulty, not face roll derp difficulty. But that won't stop lazy self entitled players jumping on the forums, when they realise it is too hard for them, crying on the forums for nerfs.
Everyone pays the same, true, but everyone has access to all the same content. It's upto the individual if they can improve themselves to a point they can clear it. If you want something enough, you will find a way. The only thing blocking you from content is yourself and how much effort you want to put in towards acheiving that goal. Not the game or SE.
