There are quite a few people who only (or mainly) have to grind exp to get to their next goal, like RB-ing.
With several players/classes being too quick for FDM AT, and therefor people take FDM AT, then do General AT to return to a full rooms in FDM AT.

That and Baron UW are the main places to grind for 40 to 50M exp. That's quite some hours.

These days I frequently see people online who all want those two areas. And that doesn't fit at all.
Sure, there is pents. That requires more active playing and more res.

Can the two highest rooms in AT be doubled? As in: create two areas for AT General and two areas for AT FDM?

PS: I heard a rumor that there even is an area already created and decorated, to the west of AT

Or even higher skeles that reflect same xp as UW?

Most non-RBs can do general, lateron FDM, but that's about it.
And some classes even struggle with good speed in AT even at RB2.

So I think most would benefit from general+FDM copy, but maybe add a Knight room too for those who want it?

The Knight room would be my choice to take some demand off the FDMs and at the same time expand the choices for characters that have seen everything...
