Ok, just have to point this out because I hear it way to often: LIGHTS IN ABYSSEA DO NOT GET RESET UNLESS YOU EXIT. The rumor of "somebody new got a killshot and now our lights are reset" is 100% false. Chests are based on who got the killshot and their specific light count.
Yes, the preference is to have new/re-entered people avoid killshots for that very reason but it happens.
If anybody needs proof, please apply common sense. If the myth of lights resetting were try the following scenario would never occur (and it often does):
1. New member gets killshot and chest drops 200 cruor
2. Existing member with max lights gets the next killshot and chest drops 1000 cruor.
See how that works? If lights were reset every following box after step 1 would result in <max chest/drop.
Yes, there are other variables that affect lights that I/we dont know about. But come on! Common sense people, please.
