[quote]Except there's a cap on the number of upgrade cores you can have too. It's something like 20-25. Otherwise I'd agree with you and say use trash till closer to 900 and stockpile but you'll reach your upgrade core limit before you reach your soft light cap. They need to remove that limit or increase it to like 100 or something.[/quote] The cap is only there to prevent players from buying a ton of them. They drop from so many sources if you bought a ton right away you would just be wasting currency.
