The Sith Inquisitor is one of the main reasons players want to play as the Empire in Star Wars The Old Republic. According to this SWTOR Sith Inquisitor guide, this class is actually looked forward to more than even the Bounty Hunter or Sith Warrior. The reason for this is simple: it is the only class that uses the awesome force lightning which has always been a highlight of the movies.
The Sith Inquisitor really has the best gameplay and trailer that I have seen yet, and they make the class look really powerful compared to other classes. One example of this is the fact that it can use the area of effect force lightning attack. Whenever I see a video of a Sith Inquisitor using this ability, literally every enemy in a very large vicinity seems to fall instantly.
Additionally, the Sith Inquisitor is the only real true caster for the Empire. No other class casts magic spells, so an SWTOR Sith Inquisitor guide really does appeal to players from fantasy MMORPGs who haven’t given up the idea of casting spells. This is a big niche audience as the Mage and Warlock from WoW were both very popular classes.
Now, the cool thing about the Sith Inquisitor that a lot of people don’t realize is that it has so many different things it can do in Star Wars The Old Republic. For example, it can handle healing and magic damage-dealing, as most people know. However, it can also spec to become a stealthy melee-damage dealer or even an evasion and drain-based tank. Not many people realize that the Sith Inquisitor is actually being built to also double as a melee class and specialization with roles beyond simply being a caster.
