"And while discussions moderator can become a higher staff position, It still pretty much makes chat moderator a redundant position."
 * If you chose to look at it that way, Discussion Moderator is just a redundant position of an Admin (or Rollback is redundant of Content Moderator) when in reality they are different rungs of the same ladder (or positions in a chain-of-command). No two rungs/positions function the same, each accomplish a different goal and a reach a different height.
