Acctually if you see the 3-2 classes you would find that they are too much over powered. In that way whatever gravity's decision is a few of them really look great. Warlocks , Gul.X are so freakingly OP that they are able to make a mob of MvPs and kill then in an instant!
In that way, a few revamps of the mechs are really required. In 2-2 classes too the Champ is somewhat a little overpowered (I know many of you wont agree with this as you are in love with champions..xD). As of the Exp rates are concerned, leveling up will be a bit more difficult. As for the rest concerned with Builts, start testing

. Simply speaking as a player, Third Jobs screws up the game and also 80% of the revamp will screw up more of it. Goodluck!
