For trash encounters, you don't necessarily need to throw enemies off cliffs to win. You can simply shorten the duration of the fight, save some resources, and still have fun. However, if you do push Minthara off, you would indeed miss out on a significant loot. It's a trade-off that players need to consider when deciding whether to utilize the shove mechanic in such situations.

Let's say it's partly based on that and partly on the player's intuition to understand which is a trash encounter and which is a challenging battle that could have valuable loot.
