considering how little a save import affects DA2 as it is, its really strange that they would even implement savegame importing if this is their philosophy. its not a matter of 'little inconsistencies'; why would they bother with importing if they dont bloody IMPORT things?! its lazy writing, no question about it. they could have gone the KOTOR route and you just select basic histories, or just kept it all ambiguous seeing as the only connections to origins are contrived side-material. as they bothered to import details, bioware either wants to make player choice important (or at least not directly contradict it) or their writers are insane and want to implement 2 mutually exclusive continuities at the same time for their sequels.
conrad verner always being renegade was a mistake; and also a bug. leliana resurrecting herself with no explanation INTENTIONALLY implemented into the game is just laziness.
either call it a retcon or a mistake; dont act like some amateur fanfic writer responding to comments that his story makes no sense. the "its my story, i can do whatever i want" approach isnt working.
