I have an alternative - don't create "onslaughts of harmless trash mobs" in the first place.Only if they add near-instant autocombat instead. If there is any excuse for RTS combat, it's dealing with an onslaught of harmless trash mobs without requiring player input.
Also make TB combat fast, no need for slow movement or long animations or other nonsense.
I know, i know. Demanding from those people any level of understanding that trash mobs are a mean to an end - not an end in itself, and that TB can be fast is like demanding Cleve to make a woke game... in a few months. Or Pierre Begue to learn how to price his games.
