So my perception was that ZOS needed to lightly trim the API. Instead, it got burnt to the ground.

You still can make Addons, however NOW you can make what the addons invision was all along. "Player UI adjustments"

Sorry if the "Instant interrupt poison arrow" or "Seeing your targets magicka, stam, and ult" are gone.

They went it with a Bulldozer when all that was needed was a tweezers.

That seems a bit extreme. Not being able to see one's own buffs/debuffs without opening the character window, or one's own incoming/outgoing damage is just silly.

So much for play how you like, I suppose.

Yeah, and the "player UI adjustments" now only include re-positioning and effects. Nothing useful.
