Dragon Knight / Rune Knight Runestone Issue

[alpha]

Is it True that Runestone can be used by other character ? because the description doesn't say it need to be rune knight.

besides from what I know IRO KRO it only for DK because need the RuneMastery skill lvl 10 to able to use the rune. 
but somehow see some other than DK using it.
is it the Rathenaa patch broken somehow?

which server you refer to?

THRO and some other PS . I do check on JRO,IRO,KRO and its not possible to use other then DK .
so out of curiosity I check from rathenaa script it  and Divine description. it didn't say it has to be a Runeknight only for using it. 
it just weird. while from what i know on IRO KRO JRO it clearly need DK job since need to learn runemaster lvl 10 to be able to use it.
