What use does the Overlord usually see versus the Nydus Worm? That is, in what capacity is each transport mechanic used?
It all depends on a player’s choice in each case. When you want try out a sneaky and clever attack on the enemy’s base, the nydus worm can be useful in that role as a more tactical and general choice for harassing the enemy’s economy. However, you can also use a mass overlord drop just like the original StarCraft, for an aggressive, all-out attack. However, the overlord drop is riskier, as you’re putting much of your supply and the cargo in jeopardy if you encounter strong anti-air defense.
