we know that there will be advantages/disadvantages based on light level of the guardian, over all. But, will the attack value of the weapons matter? For example, if I equip a Y1 red death (170 attack) and i'm at light 285, will i do the same damage as if i equip a Y2 red death (280+ light) and I'm at light level 285. I know in PVE, given a high enough enemy light level, the damages would be different in this situation. Not so clear in IB. And given the minor differences in damage scaling based on guardian light level (maybe 6% difference with 30 light levels), i there is no weapon scaling, it leaves the door open to equip a single Y1 weapon in IB, if you so choose.
