The Vanquisher is the pain train and successor to the Berzerker: he can inflict insane amounts of damage in a very short time span.
However, to maintain this high damage he has to carefully plan his attack since many of his new skills have a fairly long cooldown. The Vanquisher's defense is his offense, he doesn't have lots of defensive skills or disables, and those he does have, usually disable himself as well as the enemy.

Important note: Destruction from the Berserker skill tree will be completely changed to a different skill that does not involve armor penetration. As you can see from the new skills below, there are plenty with armor penetration and even some that are similar in a way to Destruction but with a much shorter active time or with some penalty attached such as movement speed reduction.
Also, take note that some skills are giving a % bonus damage instead of a fixed amount. I have not included the actual figures for bonus damage as they will all be tweaked once all classes are finalised.
