wouldn't it solve all this trouble if at level 50 dungeons a new player awarded a boost to tombstones and gil instead of the exp that no-one can use. A tank may leave if they're going to lose out on tombstones/hr, but the same ones will probably happily stay for a boost to it. Players should be rewarded for helping out newer players. If SE is against this, another one they could try is that tombstones received in the dungeon don't count towards the weekly cap. We'd never see a party die due to a new player, we might even see FC's advertising to take new players though content to show them the ropes for that bonus/tombstones above cap.
