The toxic Pagos bottleneck and how to solve it

[Iscah]

An alternate fix would be change the kill credit system which is the root cause here. If you hit the mob and it dies, you get your credit. Make is similar to NM/Fate credit system.

Party does less than 10% damage - Bronze effort, 15% chance of feeble light and 25% XP.
Party does 10% to 30% damage - Silver effort, 30% chance of feeble light, 10% chance of gentle light and 50% XP.
Party does more than 30% damage - Gold effort, 50% feeble, 20% gentle, 5% bright, 100% XP.
Actual numbers are my suggestions and have no expectation of being used.

I thought this is what already happened (approximately) with monster EXP? First person/party to hit it gets 100% credit, everyone else gets credit according to how much damage they inflicted?
