The exp from raids is now non-existant, there is virtually zero reason to do raids now before level cap as the rewards are far worse than dungeons. They take longer to do and give barely any threads you get a CHANCE at meta gems (buyable and finite) and a CHANCE at better quality loot (that has +2 main stat from the free loot from quests)
Hopfully this is a bug or you basically just DOAd raids in remix.
