I may be in the minority here, but I would love to have a universal Destiny account that would allow me to carry over my progress, character build, levels, and RNG loot collection between multiple platforms.
I have many real life and online only Destiny friends that I play with on both Xbox and PS4, but its such a huge time sink to bring your characters light level up to a playable state for high level strikes, raids, and Iron Banner matches.
And of course the countless hours spent on collecting a decent amount of high quality RNG-based exotic and legendary gears.
From a business standpoint, its understandable they cant carry over content to and fro different platforms that involve real money purchases such as silver coins (micro transaction currency), season pass, and paid DLC content. Those can be locked per platform until you own them on both platforms (first parties still need to get their cut from the sale).
In summary, itd be super awesome if I can carry over stats, progress, and content ownership that doesnt involve real money purchases across multiple platforms. It would be such a huge time-saver. Ill even gladly pay for such feature.
EDIT: To be clear though, I am not upset at Bungie at all. Theyve provided countless hours of enjoyment with D1 over the years. I have faith they will do the same with D2 and make tweaks, changes, and feature additions over time.
