How long can you grind?

Listen to music, chat & vent alot..

I've used to grind 15 hours or more daily, longest being 50+ hours (Not exaggerating) with only about 5 hours break (During 2x Events). >_>

Of course not proud about it, but it used to be all about the exp. ;x

Good that I've changed.

 Spoiler

I remember seeing a topic or more like this on Sw, but you might wanna add a poll if possible.
