You may have become stronger. Comrade does less as you get stronger, because 9999 damage is more devastating to a person with 300HP, than to a person with 70000HP. So you should go for the HP spheres last, or you could customise a weapon with Overdrive -> AP, Double Overdrive, Triple Overdrive, and Triple AP for maximum experience.
