I don't think OCRA is going to be any good. Every campaign excludes at least one rank, so OCRA would be everyone. Of course certain ranks are still allowed in some like 777coin, but there is no payment option for them, so they don't get paid much for what they are worth. Maybe for 777coin for all the other ranks simply put the highest tier of pay for all of them.
OCRA would only be used on campaigns that are (almost) full, for example DiceBitco.in and PrimeDice. This does proof that I need to come up with a better name for it, because it seems to confuse people.
Had a bit of fun with it looks a bit different since it kills all the other ranks but Legendary and Staff
Gave it the brown designation and put it either as a special category with the brown example or as a Bolded subheading then listed as an active campaign in its own category
Seems like a good idea format wise but final decision lies with you just felt like tinkering with it to see what it looked like
Pardon the 100 edits to the page if you were looking at it the whole time (Think I got all the info correct now ^_^)
Also S stands for Senior so what would Staff stand for.
@William does it look complicated now just curious maybe it could use a more clear name.
