Diablo 4's new Whimsyshire portal shows the problem with drip-fed content
The Cuddly Conduit arrived weeks into the season, leaving some players struggling to go back to Whimsyshire.
Diablo 4 Season 15 has kept us busy with all the amazing secrets we have found. With Patch 3.2.3 on October 14, almost a month after Season 15 launched, Blizzard added new cosmetics. We got the last part of the Bovine set, and a portal you can obtain from Whimsyshire. While you can easily get the Bovine set with a little farming, the town portal cosmetic is a whole other problem.
And this points to another important issue.
Releasing content in patches is perfect to keep players playing, but the content needs to be accessible to everyone easily. And you can barely access Whimsyshire, even with hours of farming.
To get the portal, you need to enter Whimsyshire, defeat the unicorn boss Neigh'relle, and get lucky with a rare drop called The Perfect Cupcake. Picking up the item unlocks the Cuddly Conduit portal skin.
The problem is getting back into Whimsyshire in the first place.
Players Already Used the Item Needed to Enter Whimsyshire
The season journey gave everyone a 
Liquid Rainbow at Rank 5, and using it opens a portal to Whimsyshire.
- Ghost of the Cow King
When the season started, you had no reason to assume this item would become so important weeks later. Everyone used it and moved on.
Now that the Cuddly Conduit is available, we need another way in. You cannot really farm Liquid Rainbow. Sure, rare portals can appear in the open world and the Diablo Hellfire: Cornerstone pop-up dungeon, but none of these can be farmed properly.
Cornerstone portals are also really rare, and getting one does not guarantee access to Whimsyshire. And even after reaching Whimsyshire, Neigh'relle is not guaranteed to drop The Perfect Cupcake.
And what makes it worse is that the cupcake could drop before the cosmetic became available. We personally saw it the first time we entered Whimsyshire, but you could not do anything with it. You could not even pick it up for later!
On top of that, Liquid Rainbow also does not stack. If you are lucky and find two in a row, you will ultimately lose one.
There is a small workaround you can use for this. You have to use the Liquid Rainbow in your inventory to open a portal, then pick up the other one before entering. It is not the most practical, but at least you do not waste one.
Drip-Fed Content Is Not the Problem by Itself
Getting new content is a good thing. It lets players come back every two to three weeks to participate in new activities or farm new free cosmetics. And that is a good idea. It is probably the best way to not have everyone finish the content in 2 weeks and then abandon the game for the rest of the season.
The problem is when it includes rare items you can pretty much waste early on, like the free Liquid Rainbow, without adding any proper way to farm that later on.
Other Season 15 rewards show how this can work. Moophisto, for example, has had more rewards added over time, but he can also be summoned repeatedly if you farm the 
Prime Rib. So there is a clear way to farm for the new cosmetic items. Whimsyshire is almost inaccessible, and it is impossible to properly farm for it.
