I had a brainstorm today…in the shower of all places…all I can say is ‘I GET IT SE’ I fully understand or believe I understand what SE is doing with the whole classes/jobs thing…and I think its brilliant…really…really…really awesome, I would explain what I think but I believe leaving it up to SE works better for all of us. So now with my new found clarity, I would love to offer some ideas:
Lancer—Dragoon; Templar
Gladiator—Paladin; Dark Knight; Assassin; Ninja; Samurai
Marauder—Warrior; Berserker/Viking; Beastmaster; Geomancer
Archer—Bard; Ranger; Dancer
Pugilist—Monk; Puppetmaster;
Thaumaturge—Blackmage; Scholar
Conjurer—Whitemage; Summoner

This is just rough thought based on my few minutes of clarity...
