Can enemies that give no EXP still drop items? (And other drop rate questions).

[Drako]

My GF was trying to farm boar skin this morning, 20 kills nothing. She was doing it on lv 50 so no exp gain. We are fearing they did something to the drops. Its not good cause she was doing that to help get her LTW leveled up.

It was a fairly consistent drop on those mobs, much better then say aldgoats.
