OK. All I have is this post to go by, copied/pasted from the Final Word section. When were these errata issued, for those in the know, and where is there evidence of such from WizKids? The errata stuff I see on their site doesn't mention either of these changes?

EDIT TO ADD
I found the May 2014 Watch List posting that made Arwen's Epic once per game. Now the question is about Gothmog's point value. . . . Where was that posted?

Fellowship of the Ring
016 Arwen
I CALL ON THE LOUDWATER! Once per game give Arwen an epic action; she can use Smoke Cloud as a free action regardless of range and line of fire, but the first token must be placed in any square on the edge of the map and she may place 1 additional hindering terrain marker per 100 points of the build total; after action resolve, deal 1 penetrating damage to each opposing character occupying a square into which a marker was just placed.

Return of the King
011 Gothmog
● Point Values are 150/100

That's when the change to Arwen was announced. It was about this time that WK stopped publishing the player's guide, though, so I don't think it ever made it into any official documentation.

Great! Found that. Now, what about Gothmog? Any idea where that was mentioned?

I believe the posting by MisterId here was the only official announcement of that. That may be what you were already looking at.

The card has the correct point value listed, but the base of the figure has 195 printed on it instead of 150.

Also note that Haldir has an errata:

Ok. So, officially, Gothmog's top line is 150? Cool. Thank you.

And to Gatharion, thanks for the reminder. If I remember right, Haldir's card only had part of the sentence written, right?

Yeah, the card just cuts off mid-sentence, iirc.
