I lost internet for 24 hours so couldn't respond in a timely fashion. By now Zion may have stopped reading but I think my point was missed slightly.
Cult Marines are largely unchanged ...
I disagree only based on the principle that I like seeing varied armies and this allows people to make those varied armies. Restricting options never feels like the way to go to me. This still allows those big fluffy Cult armies, the mixed armies and even the armies without any cult units. It's legitimately very well thought out and nowhere near as bad as this knee-jerk reaction from the community is claiming it is.
From the whinging I've been reading online apparently cult units where WAY better back in the worse codex when they cost more and often they had other issues.
I'm not talking about "in comparison to last edition". I'm talking about in general. Cult Marines just feel underwhelming, and I think that it's because they're straddling a line between Troops and Elites. They had this problem in the last codex as well.
Take Terminators vs CSM. What changes? Better armour, better weapons, more attacks, higher cost for the Terminators. On the other hand CSM are cheaper, score, and are relatively disposable and generalist.
Terminators, compared to CSM feel elite
. They are deserving of your Elites slot. They accomplish different things to CSM, and do different jobs better/worse. Chosen, although not very different apart from the 2A base, have a zillion and one options to make them specialists at anything, from quad-melta Rhino-bunker to demi-Death Company CC specialists. Again, they do something regular CSM can't do.
What do Zerkers do? They're CSM with Fearless and WS5. That doesn't feel "Elite". It feels "same old". CSM can fill exactly the same role for exactly the same cost, and both can score. If Zerkers had had Chainaxes as standard, they could have had a niche as "CC anti-horde unit". As it is, you just think "What's the difference between a Zerker and a CSM painted red?" and the answer is "not much". And that's a shame. I think the team writing the codex were resting on their laurels a bit regarding the cult marines. They could have got some new toys/abilities etc to take advantage of the new edition and instead got copy/pasted from the old dex with barely a change, and that's just a little disappointing. It doesn't make them unplayable, or terribad, just a bit "Is that all?".
