Buffing isn't tedious for those who get their Life and sometimes, Creature, from Arcane Lore. You hit buttons sequentially, 8 times for armor, and 3 to 4 times for a weapon. Takes about 2 minutes or less. Lets you focus your xp into more specialized areas too!
Insofar as life without plugins is concerned, BTDT for about 3 years straight. Then I came to my senses.
I don't want the game played for me, but a magically automated wood-chipper that dealt with my salvage would sure as hell be a quest item I'd go for...weekly if I had to.
And CORPSE TRACKING for kills, especially for mobs that get stacked, should be a given...I should otherwise be able to pile the bods neatly after looting...

Automated loot scanning is nice too, but it's the corpse tracking I really like for increasing functionality for looting.
Now, for live trading? Pfaugh! I used to have time for it, but not anymore. Still, it'd be neat to see it again. Always made extra time for a good haggle!
