For whatever it's worth, I wound up playing the trilogy pretty consistently 60/40 Renegade/Paragon and never felt locked out of any major character/story decisions for it. I feel like the whole issue of min-maxing it has kind of been blown up beyond what the game mechanics actually ask of the player.
The whole thing with Jeff trying to puzzle out "D.Va Cup" and the kicker of Ben not actually finding out what it is was incredible to the point where I'd think it was a bit if their confusion didn't seem so sincere
I'm gonna add another vote for finishing up the story now and then doing a bonus episode or two after in Premium Adventure. Both to keep momentum going and also because you can change outfits. Which is super important, obviously.
