As far as for what members we use for each war, I think that certain members should have higher priorities to enter a war... I think that we need a separate ranking system for the team in itself... I think what we could do is have three ranks...
String 1 - Only 4 members can be apart of the first string, and these members will be the ones guarenteed to make a spot in each war...
String 2 - Only 8 members can be apart of the second string, these members will fill the spots left vancant by the first string by first come basis.
String 3 - Everybody else will be a part of the third string. Thrid string members can only join wars if there isn't enough 1st and 2nd string members to fill the amount needed.
Each member can raise themselves to the higher string position by challenging for their spot. So tell me, what you think of this ranking system?
