I get to run milestones for 6 weeks to get 700 and get enough infusion fodder and cores to bring the gear I really want to use up to that LL. Just to turn around another 6-7 weeks after that and do it all over again. I'm just starting to feel like Sisyphus. Enhancement cores aren't the only problem, it's really that this game is so dry on loot that all there is to do is chase numbers.
