i have a couple suggestions for very slight adjustments that will allow even small spurts of pagos give actual progression rather than requiring you spend 2-3 hours grinding nms that never pop or being in a train that goes nowhere

1. give all xp kills the lowest light gain level, this way people are always moving forward at least a little

2. give chains a similar crystal drop to anemos, even 1-3 gained during a 30 chain goes a long way for those trudging through 15 pagos weapons

3. allow light crystals to be traded in for pagos crystals, that way if you hit a bottleneck due to not enough people running nms (or those nms never spawn even though theyre prepped) you have another way to get crystals
