How about ex-Legends who are not in legend status now, can their names be taken away?

Who are the ex-legends? Im pretty sure legendary status hasnt been taken from anyone yet, doubt that it will.

But even then, the name has serious history behind it. For example, if 3 letter namechanges were done I doubt they would give you vebs name.

Would it be possible that there is reductions on the namechanges?
(Sorry for my bad english )

Do you mean as in you having to pay less for it?

If so, then no, probably not. Namechange payment is there to sink the TC, that is why it is such a high price
