RS has crystal bonus for RS event, bls has crystal bonus for points/ standing. WS has sadly also lost crystal bonus afaik (haven’t played much lately).
Crystal bonus in YS was for those who bothered to ship manually and was a great motivator to ship manually.
Either bring back daily crystal deposits to planets and somehow negate them if relay used, or introduce a scaled, monthly bonus amount that rewards with crystals relative to average shipment bonus achieved over that time period.
Devs seem keen to get people to play different game modes, Crystal rewards are a great motivator.
