I do em if I need em.

If I am a bit low on exp, which I find happens often in outlands, or if they lead to a large chain. Or if I just need to level skinning and LWing and might as well get some exp out of it!
My 4 yo brother used to do some for me while I sat beside him reading or whatnot, but getting your own small child who likes to kill velociraptors is not recommended, they are rather slow after all, and have difficulty turning.

When it comes down to it, if I need to, or am in the mood, I do them. Most of the time, I don't.
