My group is basically the most unoptimized it can be due to having to replace a member (lost our WAR right when we started learning A2S). It's DRK/PLD/NIN/MCH/BLM/SMN/AST/SCH. We are starting on A3S. We're aware of the unoptimization, but our group is more casual so we don't push for people to switch jobs unless they want to.
