I think those are more of an aftermath due to how the scope of the redesign for the cross-role system went. Kinda makes you wonder the depth of view they have.
Oh yes I know the nuances would not make it optimal, but then again I am not advocating scourge brought back from the dead either. The same redundancy issues you point out for Scourge are the same that can be pointed towards a raid TBN.
And on the note of troubles with removing things. SE just might go through the trouble of removing gauges from the game, from a feature, they went to a minimalist approach, then back to how it was before 4.0; likely by 5.0.
