So there had been several mentions of previous tier armor having a penalty vs. current tier armor.
For shields this was obvious as you can put on a fabled T7 shield with higher stats in everything and then put on a treasured T8 shield with lower stats but see your avoidance go way up (particularly in block).
However it was mentioned the same went for armor. I was looking through my bank and found two bps with the exact same mitigation of different tier:
LootDB.com | EverQuest II Item Database - Hurricane Forged Cuirass
LootDB.com | EverQuest II Item Database - Breastplate of Ravaged Onslaught
Putting them on I saw no difference in mitigation. So was just curious if the tier penalty/bonus applies only to shields? Does fabled for armor make a difference to bring it up a tier? Do weapons get affected also? Just seeing if there is a definitive answer out there.
