Why is Square Enix so lazy with making weapons lately?

[Tsiron]

GNB and DNC should have Nidhogg, Alexander (x3), Warring Triad (x3), Susano, Tsukuyomi, Four Lords (x3) and Omega (x2) weapons, but don't
RPR and SGE are missing Shinryu, Tsukuyomi, Four Lords (x3), Omega (x2), Titania, Hades, Warrior of Light, Weapon Trials (x3) and Eden (x2) weapons
VPR and PCT meanwhile released without Hades, Warrior of Light, Weapon Trials (x3), Eden (x2), Hydaelyn, Endsinger, Four Fiends (x3) or Pandaemonium (x2) weapons...

Probably some I've missed but that's that much bleaker if so, isn't it...?
