I am not lumping all of the notes as confusing, but this particular section which seems to state one thing, then immediately contradict itself. Reading between the lines, it therefore seems only a few motifs drop rates will be lowered significantly enough to warrant the first part of their statement (quoted below), but they list a big list of motifs without identifying which are actually affected.
Initially you think all are affected, but in their very same paragraph they say the rates are lowered, they then say that for "most' it is marginal.
**from PTS patch notes***
"With the release of the Outfit System, we've adjusted the drop rates for a number of Crafting Motifs to help ensure certain impressive or prestigious Motifs retain a degree of rarity. In most cases, this reduction is marginal. This change affects the following Crafting Motifs:
{list of 14 motifs}"
Statement 1 - ZOS says lowering drop rates of 14 listed motifs so they retain 'impressive or prestigious' rarity. Ok, so far, straight forward. But...
Statement 2 - 'In most cases, this reduction is marginal'
This is typical ZOS double-speak. Without arguing whether lowering the drop rates is good or bad, all I am saying is if statement #1 is true, then statement #2 contradicts it.
Unless of course you connect the two statements much like a venn diagram and include only the overlapping section and exclude the non-overlapping sections.
e.g. They listed 14 motifs - yet said 'most' are only affected marginally. Which leaves the conclusion that if the word 'most' is used correctly, then only a 'few' of these 14 listed are significantly affected (with the rest as stated, only marginally).
So what is the point of listing 14 motifs when by self admission most of them will only have 'marginal' adjustment to drop rate? Why not just list the 2-3-4, the few, that really are lowered in drop rate enough so that statement #1 would legitimately apply? Are we to guess by trial and error which of the 14 are only 'marginally' affected and which are the ones really nerfed?
Given how large the impact of RNG is, even reports by players will be in doubt - player A could say it is X, Y, Z that was truly lowered, and player B would say no it is only A, B, C. So ZOS - if you're going to make a change, and list it in patch notes, why make a large list where you self admit most don't apply, but don't identify the ones that actually do?
