I think the reward always was 3 tokens, but the target was 1000 points, even though the mission text said 2500. Then MA fixed the inconsistency by increasing the actual points to 2500 too.
The Feffoid cave went down from 5 to 2; the Daily and Big Mining are still 5; that leaves the Daily Poacher at 5, which now looks the best value. The Ringhorn is above my level.
Btw, the low-level Thorios in the LAs SE and SW of Neas also count, slower but a lot easier than the lot N of Fort Victoria, so this mission is achievable by less skilled players.
