BST is heavy armor class just look at Tartarus Platemail as an example

1 armor does not a heavy make. The heavy classes are: PLD, DRK, SAM, DRG, WAR

While BST does get a few 'heavy armors', more of it's armor sets come from the Medium classes. You can use Dynamis as an example as well, The ones listed above are proc.ed by WS because they have high HP and DEF. While MNK, BST, THF, RNG, etc are JAs :3
