1 - It's really easy to dodge those bullets 2 - They aren't exactly invisible, you can see them pretty easily 3 - VoG has enemies teleporting as well and it doens't make impossible to kill praetorians (unless they glitch) 4 - Enemies taking cover won't make a raid harder 5 - Thralls chases you as well and it's only 1 shot to the head + Jumping to avoid being hit 6 - Same as 5 7 - I don't remember vandal snipers taking cover, they just stand there and shoots at you until you kill them 8 - Teleportation again? 9 - What? 10 - Shanks won't be shielded, just like harpies aren't shielded on VoG and Knights aren't shielded on CE. I do think the raid will be the same difficulty as VoG instead of the same difficulty as CE (easy - normal), but I don't think you have good points. After CE, they will probably learn and make more mechanics to make the raid harder.
