It would be nice to have a cash shop item that removes the homunculus time limit of 30mins per summon. Its purpose I would assume was to avoid afk-ing and since its pretty useless afk leveling its just more of an inconvenience than anything. Homunculus are a big part of alchemist identity and i do not see why there should be a limit to it. Keeping the summoning requirements(seed of life) is fine as punishment for not taking care of the homunculus and just get it killed everytime.
