The 100% experience buff Winds of Wisdom doesn’t work for me. I level up my three alts and I always get the basic amount of experience. For instance - if a quest gives 30k exp I get 30k instead of 60k. I checked what’s the basic experience reward for a quest or invasion quest on wowhead at my level and it says 30k+. I don’t think wowhead updated the quest rewards for the buff time. I should get double of that .

I played few alts yesterday and today. It randomly works for me apparently.
For my 110+ alts it doesn’t work for quests or invasions. It worked for random dungeon - i got double exp at 115lvl (200k and it said on DGF that I would get 100k)

For my 105 for some reasons it worked - I was getting double experience for Legion Invasion. I remember I was getting two numbers above my head with the exp and doubled exp points.

The rested bonus doesn’t seem to work either…
