Wow, you guys were busy while I was sleeping. Very nice, that makes me excited. :D So I'll go ahead and address a few things here. 

1) The diversifying aesthetic of the rangers will be which color they represent on the color spectrum. Rainbow wavelength bee-yotches! This also means that there won't be a black ranger (being as black is the absence of color) and green will be in their place. 

2) In terms of weapons, everyone be will have a blaster and an energy shield come standard. Each ranger will also have a personal weapon made of hard light, which can be whatever the player chooses at character creation. Sword? Hammer? Halberd? Nunchucku? Claws? Bow? So long as we don't end up with 5 swords, make it whatever you want.
