1. Make viability more of a achievement, than something earned too easily.
2. More after game interaction with NPC and love interest.
3. More causal outfits for your character to buy and wear on Aya or the nexus.
4. Apex strike team and cryo pod terminals on forward stations or in outposts.
5. More alien species in andromeda different for previous aliens and more male human or aliens love interests for female characters.
5a. For the dialogue they could of had something similar, but different enough from Shepard paragon/renegade like for Ryder it could be impulsive/reserved which would seem more fitting to Ryder's age and inexperience as a pathfinder.
Sorry for the added top five but it need to be written.
