So, the mongol tech is all about mitigating the time that the mongol structure spends traveling from point A to point B. It never embraces the journey itself. So instead, what if the journey actually mattered to the mongols?
Nomadic way: This tech replaces the mongol speed boost tech from oovoos. Instead of increasing speed, whenever a structure packs, it marks the last location it was set up at. When the structure unpacks, it gains a buff, based on how far it travelled from the last location it was set up at.
Tier 1. The structure can instantly create 1 unit and resources dropped off are multiplied by Z if they have moved X distance from their last camp location.
Tier 2. The structure can instantly create up to 2 units and resources dropped off are multiplied by Z if they have moved X distance from their last camp location.
Tier 3. The structure can instantly create up to 2 units, resources dropped off are multiplied by Z, and the structure gains creation speed and health regen for Y time if they have moved X distance from their last location.
Additionally, the structure move speed is heavily nerfed, thus making the mongol TC rush nonviable.
