It's probably already been mentioned somewhere, but getting 73 datacrons on all 8 of my characters is brutal. You could make it super tough, Legacy 50 requirement, cartel coins, both, whatever, just tough to get groups now to get them all and if you got them on one character and have lots of Alts, I think there should be a legacy perk for it.
Please let me know what you think.
Thanks!
