Legitimacy when it comes to leeching?

I was against leeching at first because all the bishops weren't really training. It was pretty frustrating looking for a bishop to train with but then again I realized if you're already 17x there's really no point of training anymore unless you plan on leveling to 200.

The people who spam smegas "B>LEECH" are the ones who are annoying and the people who are leeching at level 14x, that's just shameful. I'm against them.
