Well. DnD5e itself also rewards good action eco. But not that ridiculously high.
If the goal is to achieve tactical movement, they do actually achieve the opposite. While its important to get advantages, it is way to obvious how to do it, and has no trade of.
What would feel right to me is a decision like: "should characer1 give up his damage and try to hold person/knock prone/open a flank, to make a setup for character 2". That is tactics. Give up something, to gain something more valuable.
Right now its: Get high ground, or move around the enemy and you have done the best possible play. Thats not tactics, thats a railroad track.
