Isn't it often the case when opponents simply get tired of playing further?

That's exactly what happens in 99% of cases. 1% is for situations where, for example, 2 heroes die in a battle with the War of the Roses, and in that case, agreeing to a draw is certainly reasonable, although theoretically, you could continue playing until someone finds a hero in the tavern or levels up a new one.
