Im in deepholm now. 82 is going much slower than 80 and 81. There arent too many painful collection quests so far but there is a lot of flying back and forth which eats up a lot of time, it seems. Im using the Zygor guide so im definitely not being inefficient.

There was some collection quest that required things whih dropped from gray blobs. I know i easily killed over a hundred of the things. They were spread out and had a drop rate under 20%. i finally used my demon lock to run around tagging them with dots and then hellfired packs of them down. It was taking forever killing them one at a time and they were too far apart for the paladin to grab more than two at a time. That quest sucked but otherwise it hasnt been too bad in deepholm. Just relatively slow.
