i was thinking maybe for the p2p battle sprites, it could be released as an expansions similar to 'Operation Crimson Hammer' where the player earns the material.

example story: finding a new battle sprite but it is sick/poisoned, you battle your way fighting the boss to get the sprite 'medicine' (the material) providing the material 3x heals the pet.

we haven't had an expansion for awhile. judging from the crafting machine for battle sprites, i can assume there will be an 'x' amount of pets and it would be nice to have more expansions =D

(apologies if i wasnt supposed to mention some things)
