Alright.

... But, there are only two ways for the lead unit to gain experience. Defeating an enemy, which uses this complicated formula, and then engaging, which only ever gives 1 exp. So you can chop and attack enemies all you want, you'll still get the same exp from slicing 3000 points of damage like holding no weapon and being struck for no damage in as many engagements assuming the unit slicing 3000 points of damage never did so while taking out an enemy unit. I do think I remember that cutting someone, even if it does not take out the enemy, gave somewhat more than 1 exp. I'm just... wondering. Oh, well.

Edit: Eh...? But... I saw Asura online a moment ago... PM him...?
