Scanning is definitely better than the Mako! I wonder if because this is through xbox game pass, and I completed me2 on my xbox 360, it's remembering that I've already completed it? Or it's just the Legendary version gives you plenty of resources to start with. Either way, you could easily get enough resources through just probing rich planets. I've now got excess resources, not bothering with any more, and there's still a ton of Rich planets out there. Trying to clear everything up before I do the point of no return mission. Want to try and get Legion on Tali's loyalty mission
. On my next playthrough as a renegade sentinel, I may even try and see if it's possible to get Legion on Tali's recruitment mission, though I guess I skip her loyalty mission then, and that may impact things.
Never played me3 before, or the 2 major me2 dlcs, trying to stay reasonably spoiler free of those.
