Those two charms are a straight 48% increase to DPS. Which will be bigger than adding another 200% multiplier.

I believe DPS is something like DPS = ( weapon + power ) * ( 1 + soldier ) * ( 1 + elemental ) * ( 1 + ( %crit chance * %crit damage ) )

Lets say you have 13 slots with 100% agility, for 1300% crit damage and you from class skills have 100% crit.

If you add 2 more agility gems you damage will only go up 14%. If instead you add two elemental gems your damage goes up by 48%.

Base of the formula above the ideal would be to balance soldier, elemental and crit. damage so that they are equal. As increasing any of them makes the others are more valuable. However as percentages available of different types of charms aren't the same.

Doing some rough math—ignoring all class skills except 100% crit, and ignoring power etc.—ideal seems like it would be something like 6 - 24% elemental charms and 9 - 100% crit damage charms.
