good guide, however, I feel that rarity depends on the indivual buying the name. A name is only worth what someone is willing to pay for it afterall.
Personally, even to me, names like "Owned" or "Lol" are worthless to me, because those aren't names I would want identifying myself or who I am.
I PERSONALLY would rather have a name like "Dark Slayer" or "Dark Warrior" or "Blood Knight"
(I am not saying these are rare, I am saying they are names I would PERSONALLY be inclined to pay a lot for)
By the way, if you think you have a name like one of the ones i described, give me a jingle
ANYWAYS, like I was saying.
Point being. If the whole of runescape blackmarketers decided the name "Lol" or "God" was the lamest names in the world, they would be worth 0g
Basic economics? The only thing making names rare is supply, and demand. If the demand is not there, the supply is no matter.
