They are changing the loot system in 3.0... from what I understand primals will be dropping tokens(I assume alongside normal loot)(each person will automatically get a token from what I understood) so if you don't get what you want after what was it 10 runs you can trade in the tokens. From what I understand Alexander normal will be more like the towers with 1 loot/floor(?)/week/person - runable as much as you want - I don't believe they've detailed the savage mode Alexander loot yet(could be mistaken).

Wouldn't mind having an extra chest that is individual loot though - with a bit larger loot pool.
