I have yet to get booted again since the first 2 days after launch, but I play mostly at night so maybe that's why. Pings go down to 30~45ms after midnight o_o
One key to making "looting for looting's sake" more enjoyable is stacking MF gear. Elites should drop rares fairly often and bosses should drop multiple rares when you get high enough. Also fully exploring a map, leaving no pile of skulls/rocks unturned, killing every mob, etc is part of the exploration/dungeon crawling experience. If you don't find it addicting as crack, D3 might not be the game for you. But you should still play to the end of the story! This time around it's really polished well.
