The previous forum version and theme *also* did not allow you to attach things with Quick Reply. I've always been annoyed at that limitation as well, but it's not new, at the least. As for the new attachment system, I agree the extra click of "Upload" is annoying but... remember back to the old system? You used to have to do this to attach multiple files:
1: Click "Add attachment"
2: Add each attachment *one by one*
If you have 5 attachments, that's 5 clicks of each, 10 total.
In the new system you click Add Files, select as many as you want. Then click Upload once. Maximum 2 clicks for any number of files (unless they are located in different folders, of course). So the new way is more efficient, though I agree in some way it is less intuitive, which is interesting.
As for the forum logged-in status being remembered, Matt has also encountered this, while I haven't. So it's quite odd. I don't really have a solution except to try clearing your cookies or at least deleting the ones for Planetside, then re-login and be sure to check "Forever".
