i.e; How many units in the Codex are actually good? Must you take certain things?

As it stands, there's one (or none, depending on who you ask) way to build a competitive Tau army. And that's why its Tier 4.
I'll agree, but your point was that Dark Eldar made them Tier 4, which I'm not sure is the case.

Is there a specific previously popular tau build that Dark Eldar have removed?

Mephiston doesn't even have buff powers, he just has to take leadership tests to use all his rules.

I take a librarian because he's cheap and doesn't pull too many points away from my power armour horde.
