[Bug] Seven titles missing from index

https://us.api.blizzard.com/data/wow/title/index?namespace=static-us&locale=en_US&access_token=

Using the “old” ID’s that wowhead.com use, the following ID’s cannot be found in the above end point.

128	{Name} the Flawless Victor
447	{Name}, Guardian of the Alliance
448	{Name}, Defender of the Alliance
450	{Name}, Guardian of the Horde
451	{Name}, Defender of the Horde
452	{Name}, Soldier of the Horde
449	{Name}, Soldier of the Alliance

p.s. Why have Blizzard moved away from the old ID’s and numbered them in a new sequence? i.e. id 414 on the end point is:-

      "key": {
        "href": "https://us.api.blizzard.com/data/wow/title/414?namespace=static-8.3.0_32861-us"
      },
      "name": "Servant of N'Zoth",
      "id": 414

where as, it used to point to:-

414	Stable Master {Name}

p.p.s. Can we get faction, obtainable, account wide, & expac data on titles too please?
