Suggestion on adding the Void to the Base Game
I like the void, its ambiance, and its design, and the possibilities it has with hook interaction and map mobility, and the addition of the Haunt prop.
It'd be cool if it was added into the base game.
However, I think it could be tweaked in such a way as to add gameplay value for the base game, such as doing the following:
Survivors that are Hooked in the Trial will appear as Hooked Haunts in The Void. Unhooking the corresponding Haunt in The Void will transport the Hooked Survivor to the Void Hook (and cause a haunt to appear and scream as it floats upwards off the Hook in the Trial). This can allow for better disengages for survivors off of Hook and act as its own anti-camp feature.
The Void itself should resemble the Trial grounds in some capacity (using tiles and assets from that same trial (acting as a kind of miniature) and try to replicate the position that a player will exit upon exiting a portal. This can allow both Killers and Survivors to exit with a better understanding of their location.
Link the Portals to Totems (outside of any Perks that may arise from interaction with The Void). Breaking/Cleansing a Totem will open a Void Fissure and once there are at least two Void Fissures, they grow in size until they become Void Rifts, and when interacted with open portals to The Void. (Or link them to Haunts that sporadically appear/disappear in the Trial, and when a Survivor/Killer passes through them, it spawns a fissure)
And significantly reduce the Time it takes for all players to perform the exit interaction with The Void.
