You'd still have to micromanage the inventory before and after every battle, you'd need to visit shops all the time (especially as, hey, shops get randomly generated stocks) and you'd still feel silly about the team carrying literally tons of loot after big battles.
Seems like standard fare for an RPG (Diablo comes to mind). *shrug* Besides, if you don't want to manage your character upgrades, then by all means, skip it. In retrospect, I found waiting for the right gear to come along a lot more engaging than having just the one or two selections in ME2, which was absolutely boring for gameplay. No fun messing around with all the weapon modifiers or armour variability. What ended up as customization in ME2 was just pointless because I had pre-order suits that were overall a lot better to have the entire time instead of searching the galaxy looking for upgrade parts one piece at a time.
Speaking of scavenging the galaxy, I always thought it disappointing not to be able to sell all those bloody resources you accumulated. The tightly controlled money and experience path that the Bioware-Reapers have set for gamers was too much. So what if I have too much money? I spent all that time bleeding planets dry of their resources!
