So you just got a new piece of gear. It has nice abilities encoded onto it, and decent attributes (+Discipline, etc.). But, what's this? Its light is lower than your current item. Is it going to be a downgrade when it's fully maxed out? Will it be a straight swap or actually be higher once if gets maxed? The only way to know is to level it up, potentially wasting materials. I propose that, much akin to the attack and defense stats, the light stat should have a current and a maximum value. This would allow us to know if a piece of armor is worth investing our time and materials in.
