I wouldn’t call this a seasonal mount as
- They remain as a 100% drop chance mount until the next expansion, well after the raid was the current “seasonal content”
- they drop down to 1% when the next expansion launches (i.e. the prepatch).
Weird how you act like you are the only one who can define what a seasonal mount is.
Not true. Sylvanas’ mythic mount is still a 100% drop chance right now. It goes down to 1% when Dragonflight prepatch comes out. That is how it worked for Jaina’s mythic mount in BFA until Shadowlands prepatch. And how it worked for Gul’dans mythic mount in Legion until BFA’s prepatch. I think it also worked that way for Blackhands mythic mount in BRF as well.
And to quote Blizzard
P.S. While the ‘Ahead of the Curve’ & ‘Cutting Edge’ Feats of Strength are going away when Season 4 launches, the Carcinized Zerethsteed (from killing Heroic Jailer), as well as the 100% Droprates from the Mythic Sylvanas and Mythic Jailer mounts aren’t going away until Dragonflight launches (The Sylvanas and Jailer mythic mounts will stay in the game, but be significantly reduced in droprate as with previous expansions).
You do love to be proven wrong.
Then by definition they are not seasonal mounts. If Blizzard doesn’t consider them seasonal rewards, they aren’t seasonal rewards.
You cannot pick and choose what is a seasonal mount or not.
