Are you guys too moronic to face the facts?
Atties are not that OP, it's just that they don't require as much (economical) micro as other civs. That, combined with a very, very strong early economy (some say OP), very very strong military in Classical make them very effective to play for beginners. Less micro certainly works for them.
Atties in 1750- are considered newbie, and their ratings are considered inflated, some say they should be -50 to -150 points lower.
Isis however, is more micro heavy, but the effect is way more devastating. How hard is it to FH (8- minutes), build an full popped army of CA's/Siege Towers and Anc/Ecl at the 10 minute mark? If done correctly, there should be no civ who can touch Isis but Isis herself.
While you're quoting all experts at this game, get your facts straight and try to think for a moment before posting mindless crap.
I am actually in the DoJo clan, and I can tell you that most of our members hate those pesky Atties
