Yeah I have about the same but there's a couple in my clan who don't have many at all and they play every day for a few hours. The only way to get them is to remember to go to spider who lacks relevance so is easy to forget, complete your clan rep for 7 cores per character (which really does help but it's a level 4 clan perk, it would have been nice to have that earlier in the grind) or fight RNG and hope that maybe legendary gear you dismantle gives 1 measly core. You're right though, it hurts the casual player base quite a bit and the people on these forums who deny that a problem exists don't help at all. They don't realise or care that more casual players are leaving the game alongside the more hardcore players that continue to leave for other reasons like the state of PvP, etc. They think that because the problem isn't affecting them, it doesn't exist and therefore people are just whining for no reason.
