Here are much diskusions about raid difficult. New raids are to hard for new players and so.
For me the raids fell like this:
Easy:
Usa
Rus.
Med:
German
Hard:
Jap
Brit
Maybe it would be an idea to bring 1 easy raid every week so the new lower lvl player can finish theire raids and the sharks can finish harder raids.
This week there are 2 hard raids, I think some players even don't play because it feels to hard for them...
