Add a training place, where you can train day by day. For example, hunters to have PVP areas and Obbys. There, you can fight artificial robots, you must learn how to counter-attack, on how to dodge some of the attacks and etc.
Artificial robots seem a bit to modernized to vesteria. Maybe test dummies like back in the old days? That would be better target practice ig.
This idea would be fun but a lot of time and effort would need to be devoted to make it work - I would much prefer development time spent on making new mobs rather than smart A.I bots personally.
