During the meeting, two waves, each wave containing a boss, broke into the room with tons of back-up. The Trooper Class “tanks” the boss, confronts the Jedi Knight adds, the smuggler help deal damage to all targets, and the Jedi Consular heals the group and buy swtor credits in the game. In SWTOR, the series of group quests and combat in general supports this style epic. A developer has released game play video shows the epic SWTOR showing a group of four players take a “boss” encounters.
There are two specializations: Sorcerer and the Assassin. The wizard seems to be the only class of conventional casting in the game because he can sit back and lots of channels Force Lightning and not need to use the light saber at all and swtor credits for sale in the game. It also has a healing talent tree. The Sith Inquisitor specializes in using the dark side of force and the class that obtains access to the Force lightning capabilities.
A talent tree focuses on one-DPS melee class with stealthy steps, while the other talent tree focuses on tanking. What you see in the list above is just what is being announced and swtor power leveling in the game. However, given the available specializations within each class SWTOR, I do not count on seeing the classes, or before the release. The killer on the other hand uses a double bladed light saber and use force lightning to charge his attacks.
