Trash mobs are only bad in Turn based boring combat.
In Real Time combat when Minsc yells and your 2-3 Melees threshing wheat with street robbers you laugh and say
"Thanks for the coins".

In Real Time Combat you are the Leader and give orders.
In Turn based combat you posses the people and make them follow your throughs.

For "follow" your throughs i have single player games.
Party games without party interaction has no value for me because they play like a hive mind controlling drones.
