1) My element levels never go above 3, how can I have more? Also, since the grid gets bigger as you go through the game and you can place spells on higher spots for + effects, does it really matter whether you actively use an element like with materia in FF7 in order to improve it or not at all?

2) How come I can't assign Consumable Elements to empty spots in the grid for use during battle?

3) How do you see in a store if the weapon you're trying to build is better than your current one before purchasing it?

4) I understand that using elements of opposite colors against an opponent are more powerful. I just don't get the circle in the upper left. Why is there green in the middle of the circle if my character is white and the enemy is strictly yellow? If the circle is fully green (which is supposed to make attacks of that color more powerful) would that hold true against a green enemy?!
