When someone revenge rdms shouldn't it be 2 slays seeing as they know they know they are breaking the rules except they don't care that they are getting a slay, if it was 2 slays then they might not revenge rdm.
Oh, then no. Only because if someone revenge RDM's, its because they don't care about the punishment afterwards, also because they are taking matters into their own hands instead of letting a staff member handle it.
but they might not do it if the punishment is worse cause they would be expecting only 1 slay instead of 2 and only certain people are known for revenge rdm
No, it should still result in only one slay. It is mainly because RDM is something staff can witness objectively. When you take in the account of whether it was revenge or not, it brings a subjective judgement into things.
I see what you're saying there, and you do have a point, but 1 rdm = 1 slay. And I think that it will stay that way.
