All Twitch Drops should be on the Plunder Pass as well, this way users don't have to leave the game to get cosmetics.
I've had Twitch Prime for years, mainly cause I have Amazon Prime, and I've probably watched maybe 2-3 hours of Twitch total in my entire life.
Today I unlinked my Twitch Prime from my Sea of Thieves account because I have yet to get 1 Twitch Drop and I don't want to start today.
By adding these cosmetics to Twitch Exclusives, it takes away what should be a reward in game, such as Merchant Alliance drums, banjo, etc.
I refuse to gain cosmetics that requires me to do nothing more than watch 20 minutes of a stream on a platform that's mainly for softc-... well, you know.
If Twitch Drops must be a thing, then they should also be added to the Plunder Pass so that players who want to earn their rewards can, and Twitch viewers still get love.
If somebody does the Twitch Drop and has the Plunder Pass, give them extra Doubloons or Gold when they hit that Renown Rank.
