BLM is the best sub for rdm, at higher lvls peoples
subs DRK when killing NMs like fenrir.
also they subs WHM for exp partys.
i would say that RDM is the job u looking for
if u like to support, so fun to play as solo and it can
be a nice damage dealer(not in exp party)
most ppls subs NIN for dual weldin for DDing mode
and also they got nice black, enfeebling
and the greatest self protect boost spells like Phalanx II
so...i suggest u RDM. oh! and u always get party invites
and bcnm invites too, specially lv40 ones
