Alot of people equate light level with skill or experience, which just is not the case. To offer a devils argument however: With the changes to the loot and infusion system a player whom has never been in a single raid can now easily reach high level. The point of putting "325+" is to try to easily find a way to filter out players whom have never raided before. There isn't a good way to do this, light level is just the least bad option. True you will not be taking any less damage at 325 then at 320, and will only be doing slightly more damage (~ 3.5% more damage per every 5 attack increase on the weapon used). True a 335 Guardian will only deal about 10.5% more damage then a 320. That is nice but isn't the point. Grimore score is not indicative of skill in a raid, Having a challenge emblem just means you were carried though that encounter one time. And sorry having a scarab emblem doesn't mean you can respond quickly in the Daughters fight. The only way to filter out players new to the raid is via light level and that is only true until we get a few weeks into the expansion. Then anyone can be 330+. Am I defending the practice? Not really. Imho KF isn't that difficult anymore. I am just saying "try to understand what they are trying to do before mocking them about it"
