So, I get most of the stuff I talk about here from a video. Here's the link to it if you want to watch it: https://www.youtube.com/watch?v=YcgtXI66ZJA, I have modified the groups to fit the server better.
Here is the Organization System: Cohort
(Consists of the Entire Faction, Headed by the Legate)
(Consists of 10 Contubernia, Headed by a Centurion)
(Has 5 Combatants and 5 Non Combatants, Headed by a Decanus)
(Consists of 4 Combatants with Handcuffs, Headed by the Highest Ranking Person in the Party)
Here are the Ranks: Legate
(Become a Recruit By Winning another Melee Tournament)
(Become a Slave by winning a Melee Tournament)
(If you want to join RP that you are have been captured by the Legion and are being "Tasted" to become a Slave)
I think the special ranks are fine, although we need more medics and blacksmiths.
