Investing on tutors is part of the game.. U don't and can't really own a tutor.. It's all fair and square.. If u have an underpriced tutor, he/she will be bought.. Unless ur in a war of course.. You should either volley or just buy back. Even better, Making The tutor overpriced is almost a guarantee he/she is urs.. But plz Don't make it a reason to bully or farm..
