considering major part of mob use -ga and aoe /nin should be always a bad sj.. anyway need test it.. /rdm on dyna should be the best sub
anyway for my opinion best sub for solo are /blu /rdm. whm for what? wyvern can breath negative status. useless you are fighting a specific mob that use 2-3 alternative status on solo. plus if you get any link you have more chance to survive on /RDM /BLU that /NIN
Phalanx/cocoon <3 + Prot/shell help alot
