World of Warcraft, in a huge move for a 20-year old MMO, has just announced plans to slowly, but surely, phase out its combat add-ons in favour of building that functionality into the main game. The sky's not falling just yet, mind, and these plans aren't set in stone, but there's a possible future in which your WeakAuras and such will no longer work.
That doesn't mean Blizzard's taking the axe to all UI add-ons. As the article linked above explains, WoW will preserve add-ons meant for roleplay, as well as quest helpers and the like. But the studio seems set to remove things that would provide combat functionality in lieu of its own homegrown options. For example, an accessibility feature that lets you do your rotation with one button at a major DPS loss.
