As for the fast unit – it's a must-have for any Chaos strategy. It's generally useful for Nature as well. And for Necropolis in Equilibrium, you should also take that fast unit, since they reduced the speed of vampires. But an attacking strategy benefits more from a well-developed fast unit. Better scouting, and you can more accurately calculate the attack time. But when defending, it's great to send a thief to an empty enemy castle))) While the opponent is trying to reach you with all their forces. However, I got sidetracked – sending a lone thief only works against AI or very inexperienced players...
