did you know that currently in crucible if you have a lower light than an enemy in crucible you will be doing less damage and taking more due to the lack of light? i dont know specifics or percentages but try it out for yourself, equip an older class item and an older ghost shell and perhaps some lower light armor and see how much damage you do and take when compared to a higher light level the numbers will suprise you.... now i'm no game dev(yet) but i'm pretty sure this means there are advantages in PVP that extend further than what was forseen....and currently warlock are the only class able to reach 180 light level(cough! cough! bungie's favorite class, cough!) try it out and tell me what you guys find and if you agree with me or not.
