The problem though is the "retreat forward" tactic. You want to get through an enemy position, so you engage them, and immediately retreat, getting back to the strategic map, where you then go forward. They can never intercept you. Or, worse, you move onto an enemy homeworld, then immediately retreat in tactical. With no strategic movement, you'd be on the homeworld sector, and could lay mines, use stellar manipulations (destroy planet), etc. That's why a retreat needs to result in strategic movement (as in SE3), or at least, restricted strategic movement and actions following the retreat.
