The language is pretty clear:

Increase [Base Stats] [Set Bonuses] of [ALL] Artifact Sets by ..... blah blah

So:

1. It affects base stats - like before

2. It is from Set Bonus - like before

Agreed.  That is how I read it, but there are people online calling the change a "hard nerf" for Lore of Steel.  To me, it reads like it might be an improvement in that it opens up some other sets (Divine Offense, Cruel, etc.).  What is the downside?  Did other sets get dropped (Like Speed, Accuracy, etc.???).  I am fairly new, and I will be selecting some Tier 4 masteries for the first time.  I do not have the spare gems to test it and then reset if it doesn't do what I want.

Please elaborate.  I have never used Lore of Steel.  There are internet posts that say the old LoS modified all basic sets (the first seven), including speed and accuracy, which do not grant 15% set bonuses.  

There are also posts saying that Divine, Immortal and Cruel were not previously modified, but that now they are.  Maybe they always were??

The new language seems clear that it only modifies the sets that give a 15% set bonus.

It works on all 2-pieces sets, even immortal and cruel, so in these cases you'll have more regeneration and more ignore def.

Thanks Valdys :).

Maybe they should Change the text then to highlight that fact (it's actually way easier to understand if it states "affects all 2-piece-sets" than the way it is formulated now ^^ ).

I hope this is actually the case, and if it is, they should definitely change the wording of the description because that is not how it reads, nor is it how people are describing it online.  

Also, by this you mean that it still modifies the sets that do not modify by 15%??   Such as Speed sets (+12%), Accuracy sets (+40), Resistance sets (+40)....

I finally went ahead and tested this on my account, and I finally understand the confusion regarding how Lore of Steel functions that I have found in online posts. The description currently reads:

“Increases the Base Stat Set Bonuses of All Artifact Sets that increase Base Stats by 15%. This increase is multiplicative, not additive.”

Many people read this description to mean that Lore of Steel only modifies the Artifact Sets that Increase Base Stats by 15%, such as Life Sets, Offense Sets, Divine Offense Sets, Immortal Sets, etc. Plarium’s description is not technically wrong, but it is very clumsy phrasing. The confusion stems from the combination of (1) The Mastery grants a “15%” Artifact Set Bonus Increase, (2) Many Artifact Sets Modify Base Stats by “15%”, and (3) The Placement of “15%” in the sentence.

A much clearer way to phrase the description of Lore of Steel would be:

“Provides a 15% multiplicative increase to the Set Bonuses of all Artifact Sets that modify Base Stats.”

I have included Before & After Pics of my Frozen Banshee to show the following:

• One Accuracy Set: 40 * 15% = 6 point increase: 131 went to 137

• Two Speed Sets: 24 * 15% = 3.6 point increase: 37 went to 41

Ohhh, you are my savior! I suppose the misunderstanding is in the wording of the description, if you are not mother tongue (like me). I don't know how it sounds in USA or UK - but when I read "[something] increases the stats of all artifacts that increase stats by 15%" I automatically link that "by 15%" to the last object of the sentence - all artifacts - so it seems the increment is not exactly specified, but it will address only sets increasing stats by 15%. In reality, that "by 15%" is referred to the increment: "increases... bla bla bla... by 15%". I can sleep better tonight. :D

• Life
• Offense
• Defense
• C.Rate
• Accuracy
• Speed
• Resistance

All those sets can be farmed from Campaign.

Those where the only sets which the game considered to be Basic Sets.

They even had a detailed list with all of the above sets on the Lore of Steel Mastery itself.

So what you people are saying is the game has changed Lore of Steel on update 1.14.

And it is now applying bonuses to Immortal Gear + Cruel Gear + Divine Gear Sets?

It's definitely applying bonuses to those sets now, yes. The current description doesn't say that it only works on Basic Sets, but rather that it works on 'all Artifact Sets that increase Base Stats', which includes Immortal/Cruel/Divine.
