Pugilist: Haymaker and Aura Pulse will get a damage increase; the combo effect of Concussive Blow, Simian Thrash and some other WS will be upped.
Monk: Dragon Kick will get a damage increase.
Gladiator: Riot Blade will get a damage increase; Goring Blade will get a damage increase and a reduced recast (80s->60s)
Paladin: something about invinicible; also their HP won't drop, but instead their INT will? Hallowed Ground/Invincible will now block all attacks except special ones?wtf
Marauder: Berserk's attack bonus and defense penalty will be increased. They're doing something with Rampage's bonuses and they will decay faster (i can't make out the gibberish it's giving me). Whirlwind's combo bonus is being changed to do something while under the effect of Berserk?
Warrior: Collusion looks like it's being reduced from full enmity transfer to partial. Steel Cyclone's TP cost will be reduced from 2000->1000, looks like the AoE range is being reduced and something about the damage and Rampage.
Lancer: Vorpal Thrust, Impulse Drive and Chaos Thrust's accuracy penalty will be removed--Chaos Thrust will also receive bonus damage on critical hits(?). Life Surge's duration will be upped to 180sec? Power Surge's recast will be dropped to 10s, it will no longer consume TP, and instead of you using it 3 times, you'll have to land 3 WS or 3 jumps. Each one will grant a duration extension and level it up (max 3 still)?
Dragoon: They're doing something with Jump--it's too much gibberish for me to figure out.
White Mage: Benediction's range is being increased.
