I`m not sure what you plan to do. So let say you have warrior 20th lvl with 15000 leadership, and want to make troll have same lds ???
If this is what you plan, i dont think it`s possible because hero lds isn`t only dependable on lvl, you have skill for lds ,medals, items . . . So how would it work if you place some item (marshals baton +1000 lds), and then replace it with some other item that doesn`t give lds. Troll lds then should change fast. Even bigger problem would be with mechanical blade that reduces hero lds by -10% . . .
Try checking how does item uho_orka ( -10% for orcs) item work and do it in reverse, so that units lds requirements depend on current hero lds. You can make unit lds connected with hero inventory and items she carry, but how to do it between unit lds and hero`s, i have no idea
