actually you can't be more wrong ferrasper. the black mage and the summoner are two pure dps caster... the only difference is the form the dps take. one is directly casting the damage, while the other relly on his pet and the dot for create a substain dps.
the trouble with smn, is the loose of the dot have affect too much them dps and lead them far behind. i feel they did hope that the ruin III will cover for this loose and the ruin buff too... sadly it's not enough. we can hope for the 4.05 a boost of the dot damage for cover this part.
