I must be tired and need a break testing all the tools...but I have come to the point where I need to launch Armitage and I can't seem to find it...Is it just me or is it really missing from BB 4.3? Thanks for your patience 
it is not missing, it is deliberately being removed due to a bug found that won't allow armitage to start. We didn't have much time to work on it and find the issue but we probably will fix (or armitage team will fix it( and release again.
however, you can always install the downgrade version.
Btw, armitage an interface for msf, so if you need it msf is there, not much we miss though. But I can undertsand that someone would like to havenice GUI bsed tool like armitage to manage msf.
