My brothers sisters hairdressers uncles favorite hooker works at SE and says all the original Classes are getting their second Jobs in 2.2;
Gladiator => Dancer (Support)
Lancer => Templar (Tank)
Marauder => Dark Knight (DPS)
Conjurer => Geomancer (DPS)
Thaumaturge => Necromancer (Support)
Archer => Ranger (DPS)
Pugilist => Thief (DPS)

As well as this, Bard is being adjusted to be a proper support Job, and party set ups will now include support instead of an extra DPS.
