You have to increase the Mission difficulty to gain more XP then, since you seemed to hit a stag.

Higher Difficulty missions, Survivals and Emergency missions have greater yields.

High level Blood Arts are the best farmed on the later missions Rank 14, 15 or Challenge/DLC/Emergency level for maximum efficiency.
