I think with 2.0 everything would be possible. There are already in game files about the engineer class, that was never added in original DBO, but could be awesome and possible to have here. About new races would be super cool too (such as frieza race) and i think with more character customization for all races and daily/weekly/monthly events people would enjoy and play a lot more. There's so much potential that would be a waste not to exploit it.
I've so many ideas anyway that developers would dizzy hahaha
