Possible paths to enhancement cores: - heroic public events completed have a chance to drop a core - lost sector chests looted have a chance of dropping a core. - strike chests have a chance of dropping a core. - first time nightfall completions have a change to drop up to 10 cores - make it dependent upon scores. - crucible matches have a chance to drop a core. - raid completions have a guarantee of a specified drop but also have a chance for higher drops. Maybe what I’m saying is, integrate the reward into the blasted game’s content that we play regularly. If your worried about hoarding large quantities, put a decent cap on how many can be stored in the inventory - just like other items.
