hmm both builds are great,
glavier: stronger attacks, more hp, statuses: dull & kb, mag.def buff
blader: higher defense, statuses: KD, bleed, (later on fear, stun), phys. def buff
bladers are harder to lvl up...but they are very hard to kill if they have decent gear.
i'd go with blader though (mainly cuz of the statuses

)
