The 7th grade armor was supposed to be released with FD, not the Moradon patch ( as it was in beta but we never actually got it yet after over a year )
TBL editing changes EVERYTHING, it's not a client side change like when you make a personal shield look like a CS. Others still see the personal shield.
Highest chances are, those are from near the end of the Beta server for RoFD, I dont know why they are such low lvled yet they have +10 gear. Also it's beta because of the tp to town scrolls we were able to purcahse from the NPC
Kunz, it's not 750 HP per armor piece, it's 750hp for the whole set. If they took off 1 of the Dragon Flight armors, the total HP bonus would go down, as well as the str, and resists. Different piece combinations give you more bonuses.
And after a little while, the top 50 NP holders in Beta were given lvl 80, I dont recall them getting free +7 sets of armor
