I have seen many high level paladin's but i see a difference in armor choice for most of them. I have also heard that the AF body is a MUCH better choice because of the HP+, but still i see many high level paladins running around in their Adaman Cuirass. I just dont see the point in buying a 700k-1000k body piece if my AF is going to be better....
Stats:
Adaman Cuirass
level: 73
Defense: 52
MP+8 VIT+4 MND+4 Enmity+3
Paladin AF Body
level: 60
Defense: 47
HP+20 VIT+4 Divine magic skill+5 Enmity+2
and obviously Gem Cuirass(+1) has +1 to all the listed stats for the adaman
