[quote]Why is it, that guardians will run last wish 100 times to get 1000 voices or run tree of probabilities 100 times to get DFA, but won't spend 20 mins to get cores. Seems kinda strange to me[/quote]. Never did neither of that things you mentioned. That's the problem with blanket, generic statements, they're always too far away from being accurate. However, even the core of your statement (pun intended) is flawed, because grinding for loot is something pleasant while grinding for a scarce material that adds absolutely nothing to the experience is a chore.
