Short answer is have the chars you want to level in your party (weak in Sub) while doing the Main Quest as it gives quite a bit of decent exp. When you have reached a point where you it's to difficult to proceed or the end of the story for now then goto Sages Tower, Flame Sprite Colony – The Spark of Battle Quest.

You see Spark of Battle is bugged and ALWAYS DROPS BOX 4, which is a 1*Soldier enhancer. Plus this is an easy quest and gives each party member 450xp. Also 2*Yoyo and Marga drop from it, then you fuse the a junky 1* you get from the AC recruiting onto each to boost them to level 2 and then you fuse all your 2* lvl 2 Marga/Yoyo onto a Soldier your leveling up for 2k exp each.

For Yoyo use either 2x1*soldiers or any 1+2* to get him to lvl 3 this nets 3k exp instead of 2k ;)
