Entropy is niche, and kind of a semi-cabal, but there are usually at least two or three active Entropists kicking around. It isn't exactly neglected, either. It's just kind of... freeform.

Scarab is considerably less active at the moment and generally harder to get into anyway, but I have nothing to do with that cabal and don't have any specifics to give you.

As for whether we as a whole are satisfied with the current state of cabals, that's both a complicated question and a moot one. There are ongoing discussions behind the scenes about changes we could make, but for now, we have what we have and we're trying to make the best of it.

If you want a low-investment cabal, the bar really doesn't get much lower than Entropy (solid roleplay is still required). Scarab is on the opposite end of that spectrum, with higher investment/risk of sinking many hours without an induction, but considerably greater rewards from a powergaming perspective.

Good luck!
