people telling me this game has better story telling and wrting than D4 are fuckin retarded that's for sure, its got better presentation, art direction, loot, skill systems ect, but writing ain't fucking one of them.
Sin and Doryani are the most interesting characters, but there really isn't much to talk about with them, Sin is as static as they come and does nothing, and Doryani isn't much more than that, good VA work, good character framing, but they don't factor into the plot, which barely exists, good lore though, the layercake that is Wreaclast's world is interesting.
D4 has multiple hero's and villains actually doing things, hero's and villains actually have reasonable motivations and actions, Lilith being a pretty easy expy to Sin in this game, except she feels useful and connected to the protag and the plot by comparison.
