The two classes of Ranger and Assassin

Ranger - quite practical class with a few aces up his sleeve (for example, it can trap and maintain a distance sniper fire). In this class there and skills are melee and distance, and yet he can heal itself. To show off their skills, Ranger must carefully assess the situation, and for unskilled players this will be a significant problem. Can move in the mode of "Stealth"!
Here's how to describe this class in two words: watch your back! Big losses for a small period of time - this is the essence of the Assassin. However, to correct them play, it is important to be able to quickly assess the situation and just as quickly respond to all. Characters in this class may also move in the mode of "Stealth", assuming that most of the skill can be applied in this mode.
