I think i have already around 670 commendations. Started to play the game 2-3 months ago as whitemage. Never got seven commendations at once, but six a couple of times. I played the ramuh story fight for a whole day because i really enjoyed the fight & music and i wanted the levin orb/myth tomes. Because of that, i did always ask if someone is new and if so i posted a macro-guide for that fight to quickly help out. I have got a bit less then 100 commendations on that day.

But i agree with some more rewards for 1000+ commendations. Would be nice to have some shiny armor pieces or accessories.
