When owning an entire set (e.g. an Adventure or Mini-set) getting a Diamond card will prompt the player to reroll their normal version. This is 100% detrimental to the player. Do not offer this.
Players don’t have the option from the reroll screen to check if there’s a valid reroll target, so unless they have the sets memorized, they will have to guess.
Rerolling here will remove a singleton from the players collection and add a duplicate. There is literally no reason for this option to exist. Offering it to the player is borderline malicious, especially when customer support is forbidden from undoing a mistake.
I got trolled by this when getting a Diamond Reno Jackson, and it’s extremely annoying.
I understand the issue. If you have the full set, you have the regular version of all the cards and they add a diamond version of one of them. You might prefer the dust, but OP might prefer to keep all the normals in addition to the diamond one. The reroll option is supposed to be in place to let you have a whole new card instead of a duplicate (or instead of dust if you are the sort to dust the normal once you receive the diamond). But if it just gives you dust because there aren’t any other new cards for you to get, you’re in a worse position because you lost the option to keep your normal and 400 dust isn’t enough to get it back.
To those confused, malicious design has a specific meaning when referring to UI. I’m not saying that the creators of this feature had an ill-intent. Just that the option provides no pro-consumer functionality, and that its existence is capable of harming the user.
And I thought it would be self-evident, but being locked into playing the Diamond version of Reno is downside for players who would rather play with the simple versions of cards.
I agree, when you already own all cards of the same set and same rarity, then rerolling is at best neutral and for some players detrimental. I understand why you suggest not offering the reroll option in that case.
That said, it is not a bug, but a suggestion. This is the bug report forum. As far as I know, Blizzard staff who check this forum tend to just disregard suggestions, because their job is to investigate bugs. So perhaps you should post this suggestion in a more suitable place.
Diamond cards are very rare, and I forgot the exact mechanism by which they are acquired. As the kids used to say, “Excuuuuu-se me!”
Pretend that I wrote “a diamond Reno that you got from the rewards track” instead of “a diamond Reno that you just opened from a pack”.
This thread is about what happens AFTER the diamond card is acquired – it seems odd to obsess about HOW the card was acquired. That’s irrelevant, no? Such a small detail. But, you do you.
You gain 400 (potential) dust because you obtain Diamond Reno. Not because of the reroll.
No reroll: 1 diamond Reno and 1 copy of each regular Legendary.
Reroll: 1 diamond Reno, 0 regular Reno, 2 copies of one other regular Legendary, 1 copy of all other regular Legendaries.
In both cases, you have one surplus regular Legendary that you can disenchant for 400 dust, if you want. Or keep, if you want.
In one case, you have a full set of regular Legendaries. In the other case, you still have a full set of Legendaries, but not a full set of regular Legendaries.
It may not matter to you, but it does matter to some. For instance to the person who started this thread, for that very reason.
The reroll does not gain dust in this case. It would if your collection of regular legendaries was still incomplete. But when it’s complete, the reroll is fully dust-neutral, but does break up a “full regular collection”. So it is strictly neutral at best, and slightly disadvantageous for some players.
