Not a fan of these numbered rankings I must say, but I totally understand how it can be confusing for those not familiar with them and Hasbro also making a habit of changing the naming of them.

I would much prefer a ranking without a number attached to it - seeing as we're all TF fans and (I assume) the guests and random visitors to this site are also, how about rankings based upon the TF 'hierarchy'

Supreme -> Rank: Creator (eg Primus/Unicron)

Voyager -> Rank: Prime (eg Optimus/Megatron/Fallen)

Deluxe -> Rank: Commander (eg Starscream/Soundwave/Ultra Magnus)

Scouts -> Rank: Warrior (eg Jazz/Astrotrain)

Legends -> Rank: Soldier (eg Bumblebee/Warpath/Rumble)

Protoform -> Rank: Cadet (eg Wheelie)

Hopefully the examples I've given give you a rough idea of what I mean by 'hierarchy'.
