Although the Dictator isn't a very popular hull to use, except maybe for players with an affinity for the Vulcan turret, it is one of the more unique hulls within the family of hulls in Tanki X.
Aside from having strong armor and is amazingly sturdy, the Dictator is the only hull that will slightly elevate your turret. The higher vantage point will in turn allow you to fire over obstacles that will stump other tanks. It can also allow you to fire off shots that can hit targets that are on slightly elevated ground, such as the very slopey mounds on the Massacre map, without the need to get on an equally elevated ground.
The Dictator is not a hull to use if you're new to teh game though as it can be quite hard to get accustomed to due to its uniqueness. Its slower movement speed may put some players off as well.
That being said, if you've logged hours in Tanki X and would like a new challenge, you could give the Dictator a try. It's more suitable to be used with a mid- to long-ranged turret, such as the Vulcan or Railgun.
