I am a big hitter and intentionally avoided mixed doubles over the years for that reason. My doubles strategy also doesn't work well as it is low down the middle on most shots with a few angles, and any popped up ball which can't be angled away hit hard directly at the opponent.
The problem with mixed is that some women seem to want to stand their ground when the appropriate play is duck and cover. I think some women want to have the ball hit hard at them by their definition, and anything above their definition is clearly inappropriate. Being married for a few years I now understand this philosophy, but prefer to avoid it in competitive situations.
