Junglers who farm a pointless lane are one of my pet peeves.

Even if you can protect Shen and keep him from feeding, do you really think Shen is going to carry us late game?

No. Go to a lane that actually matters.

And then it's really frustrating to have your jungler farm a lane an entire game, and have that lane lose horribly anyways.

Junglers need to be better at assessing things, not just automatically ganking top lane first because they're on purple side and started blue buff.
