It’s been one of those days… here is another deleted post probably to be followed up with a heavily edited post.
From a design standpoint, this is what you want, right? If there is ever a rare drop in the game (or something just difficult to earn), then you don’t want the BMAH to become the better source for this item. The intent for the BMAH is to give players an additional chance at the item – not a better chance.
There are millions of players who play this game. Each with their own level of skill, gold-making ability, preferences of types of content, and availability of time. Whenever the development team designs a Mythic-level raid, they don’t center its overall design around the player who has an LFR level of skill. In fact, they don’t even design around the average player’s skillset. However, the opportunity is still there for players to push to a Mythic level – if they want to. Also, the transmog appearance specific to Mythic is only available from Mythic-level difficulty. This content becomes available to most others around 2 – 3 years later when the content is soloable. This is your preservation of communal value transitioning from Skill-Based Difficulty to Time-Based Difficulty.
The same is true for players who really enjoy the slot-machine style of RNG. This type of hunt on this level is content that is enjoyed by some within the community. I believe Mythic raiders make up 1% - 2% of the community, and yet there is an entire tier built specifically for them (and anyone who want to go to that level). So, it completely reasonable that a handful of mounts require an extraordinary amount of effort for those wanting to put in the effort. However, as opposed to Mythic-level raid transmogs, this content was available to everyone from Day 1, because it is Time-based content outright. So, the communal value is preserved because its Time-Based difficulty that isn’t forcibly changed. The compromise here is that there are 800+ mounts currently in the game for those who find the MoP WB mounts and X-45 Heartbreaker excessive.
Again, this is all for the standard bell curve to 2 – 3 standard deviations. We will cover bad luck protection later. I just want to focus on value preservation more than anything.
