Looting while solo doesn't take terribly long. Right click, two-three clicks, no thinking, done. Sort loot later, or take a minute if you're full up to drop junk. Mushrooms takes a bit longer if you're mining, but not much. I guess I should point out I'm using an AOE build, so that shaves some time off. I am happy to hear the upper-level dungeons take a bit longer, but not as long as, say, a 6-hour EQ Plane of Hate/Fear raid.
