I hope there will be no morality system in Andromeda. But if it's going to return, I hope paragon will be more like Anderson and renegade will have something from the Illusive Man and Saren (I can't play as renegade in ME1-3 because I feel like an complete idiot. I want to manipulate people, not to shoot every single NPC just because I'M AAAAAANGGGGGRYYYYYY).
I'd like Paragon and Renegade to decide what they're trying to be, and then stick with it.
ME2's tone-based morality was annoying on multiple levels, because views and alignment would flip-flop in the same exact same missions or conversations (Legion's loyalty mission where the Big Decision counters the buildup, conversations with TIM), and yet the P/R point percentage system rewarded P/R consistency over keeping your rhetoric consistent.
But it also hurt because 'nice' and 'angry' really, really didn't work out well with simultaneous themes like 'follow the rules' or 'ends justify the means.' In almost all cases dealing with strangers in the ME series, Paragon Shepherd is a 'by the book', procedural, and legalistic person: defer to legitimate authority even if you disagree, follow procedural justice, don't break the rules, tell the truth, etc. You even chastise more than one rule-breaker and generally wield the 'I am the side of Justice!' banner of incorruptibility...
...which goes out the window the moment any friend/companion is involved or it isn't 'nice.' Tali's trial is the best example, in which the Paragon 'nice' option is perjury, the coverup of war crimes, and enabling the resumption of said war crimes by members of the Admiralty board. While the only option to, you know, tell the truth of a real crime to court is the (non-persuade) Renegade option. Not because it fits any of the Renegade themes, but because it was 'mean.'
The logical convolutions to keep Paragon and Renegade consistent were disgusting at times- all the more so because ME1 and ME2 had an extremely heavy imbalance of tone and content in favor of Paragon choices being just as good or better in terms of consequence, tones, and even player content and rewards.
Renegade bounced between 'racist jerk' and 'extreme pragmatist' in a series in which pragmatism was never the most pragmatic option until ME3, and in which most of the 'racist jerk' stuff wasn't even pragmatic. It failed it's own ideological claims test. Paragon bounced between 'ideal upholder of the law' and 'best buddy ever, nepotism rules', and deep-dived into hypocrisy and double-standards that were never called out or addressed.
