Quit crying about cores. For any NEW or RETURNING players. Everyone has to grind to 50 so any cores used before then is stupid. Tell the new players to go visit Werner-99 he gives you 690 gear, equip and go do public events for better gear then start working on the Forges. The Forges provide weapons and armor. All gear acquired will be high enough to do any activity with Match making. If you follow these steps you'll be 700+ in a week. And I never one time mentioned Enhancement Cores, trust me they'll drop while you play.
