Spines Customization - Unlockables.
Along the same lines as unlockable weapons? I could get behind this, if it's technically possible.
As far as I know, you can't classify a power for both *Weapons* unlock and *power customization*, but I'd think it possible to create a *power customization* that requires a badge, level, *unlock* etc.
Would it be possible to get Custom spine design unlockables? Energy spines for Vanguard, maybe black spines with writing/symbols on them for Rularuu, etc?
Because this would make my day.
