Do bols still disease? Before the CU went live, I was getting hit by the odd bol, and I'd get a disease that would last until I had relogged several times.
The disease tick was so low that I let it just run for four hours while village grinding (it was a pain to have to have a doc reapply buffs upon logging out-buffs didn't stay active, but rather were cleared upon logging out).
If they disease, I'd say go for easier game like the pickets. Using a ranged attack/droid or pet to draw a single mob from the group isn't hard (with aggressive mobs, just walking to within 22m of ONLY ONE, then waiting for it to aggro you so you can pull it away also works), so you can hunt even social mobs without much difficulty.
