Would you like to see twitch drops enabled for Ashes release? Before release even? Why? Why not? And if yes, what type of drops? I've seen New World, Elder Scrolls Online and many other games offer them. It's essentially a marketing tool.
What are Twitch Drops you may ask?
Twitch Drops enables you to grant in-game rewards to the Twitch community when streamers play your game or when they complete in-game missions, such as conquering a particularly difficult part of the game or by claiming victory during a battle royale game.

For example, if you watch your favourite streamer with drops enabled for X hours playing Ashes, you get to claim a reward if you link your Twitch account with Ashes, or you get a key to redeem.
