Wow... so many n00bs in this topic that have no clue what they are talking about.
Joymax made this game to favor the INT over the STR, so yes INT builds naturally have higher balances than STR.
Here are the highest balances for each build (pure types only):
Pure STR Glaive or Archer
109% Phy Bal. maximum IF 350 out of 351 possible STR pts
46% Mag Bal. maximum IF 142 out of 144 possible INT pts
Pure STR Blader
110% Phy Bal. maximum IF 355 out of 356 possible STR pts
48% Mag Bal. maximum IF 148 out of 149 possible INT pts
-----------------------------------------------------------------------------
Pure INT Spear or Archer
64% Phy Bal. maximum IF 142 out of 144 possible STR pts
113% Mag Bal. maximum IF 349 out of 351 possible INT pts
Pure INT Sword/Shield
65% Phy Bal. maximum IF 147 out of 149 possible STR pts
115% Mag Bal. maximum IF 355 out of 356 possible INT pts
