We will find future avenues to get the items from these that still have value to you, I know the Red-painted Steed is expected to arrive in a future reward track. The Pick a Mount box will need some discussion. Anything else?
I thought when you guys originally said you were removing these Lootboxes from the game that you'd mentioned you'd add ways to get the various items in game at a barterer.
I don't feel like 'Reward Track' is a very reasonable replacement. These were acquirable in game, now you're moving them to "oh if you're playing at the right time, you can get them from the Reward Track, otherwise zero chance.". That feels like a disingenuous way to hold to your word.
It's the same thing with tradeable Tomes of Defence. These were the main ways to get those. Even after you removed Sturdy Steel Keys from being acquirable in-game, at least we could buy them in the store and then trade the Tomes of Defence from opening Lootboxes to our friends (or sell them in AH, as some do).
Now those are essentially Store Exclusive (outside of a super low drop chance from Hobbit Presents for Bound to Account ones, and an extremely low drop chance to get a tradeable one from Traveller's/Adventurer's Lootboxes).
Almost all Raiders use Tomes of Defence at higher tiers (especially for Tanks), so this sorta becomes a 'Pay To Win' option since you're removing ways to acquire them through mostly in-game means.
