Patience is the most valuable trait of the endgame player.

Typically, in the last round of open tournaments the level of play is markedly lower, the number of blunders higher.

There is nothing wrong with trying to exploit the natural human tendency to become impatient when forced to play a boring position.

Sometimes players need to gain time on the clock by repeating the position, but most often its purpose is to wear down the opponent psychologically.

The business of the endgame is maneuvring to control critical squares, advancing or blockading passed pawns, preparing a breakthrough by the king, or exploiting the subtle superiority of one piece over another.

Patience is the most valuable trait of the endgame player. In the endgame, the most common errors, besides those resulting from ignorance of theory, are caused by either impatience, complacency, exhaustion, or all of the above.

Agreeing to draws in the middlegame, equal or otherwise, deprives you of the opportunity to practice playing endgames, and the endgame is probably where you need the most practice.
