Just feel the need that to point out that you are missing some of the rewards the characters you mentioned received and in some cases the rewards came earlier then you mentioned. Just think it clouds the issue a little to have an incomplete picture.

Also, I wouldn't normally consider something like a tattoo or becoming a Maran, (or Provincial like Gwildonian) to be rewards. Those for the most part are normal character progression for characters in those cabals and/or actively following a religion. Essentially most characters should be able to achieve these if they try and put in the time. They are not really on the same level with earning a 3rd legacy or quest form or something like that.

Personally I have no issue with respect to how rewards are handed out. The characters that I have interact with over the years that are high reward earners are in almost all instances very high quality characters, making me believe they deserve what they have received. Regardless of who the player was behind the character.
