An alliance raid for people who only do their roulettes and dailies where everyone can screw up is called normal mode, which dropped earlier this patch.
In your post you mention BA/Bozja which are normal difficulty content. If your point is that you want more exploratory zone content, I totally agree and that content is confirmed to be on the way.
If you're asking for them to bring back Hard mode however I would have to disagree. The current pipeline of normal/expert/alliance/extreme seems reasonable to me. If you can handle the latest alliance raid you should be able to handle an extreme. If you can't do that then you're not ready to move up. Creating a difficulty that is marginally different than normal isn't going to help that issue.
