You don't really get enough echo to help players who don't have good teams catch up. Only on the fights older than 6 months do you get 50% echo which makes a difference. The 25% on extreme primals and current 15% on old coils isn't really making a difference. Nobody in my FC has beaten T5 or Ifrit extreme yet, while the top raiders are already farming the last turn of second coil for i115 weapons, so I think the gap between players is still getting wider. I couldn't expect to beat the last turn of second coil until maybe 1 year from now, dependant on the amount of adjustments that are made, as I have no elite static and rely on DF for random player parties so the content has to tolerate people making mistakes and not working perfectly together as a team.
