The type of troop deployment is located in the hero's window, in the upper right corner. The speed doesn't decrease, of course, but it's not as powerful as in Heroes 3. It's a matter of skill; you need to get used to the combat system of Heroes 2. When I first started, I couldn't complete the scenario. I thought, "What?" After a few games, I got the hang of it. I also have enough money for everything (collecting from the map, capturing cities, and mines). Sometimes, I even accumulate tens of thousands.
