Hunter
The Hunter is a class that finely balances up close combat with other powers that encourage long distance, single target damage. This is the most agile of all the classes in Destiny, as it can obtain the ability to go invisible instantly or roll out of the way. Being on the move is always one of the most important parts of playing a Hunter, as it allows you to make use of a lot of the tools at your disposable. Along with this are a variety of grenades and supers that span a gambit of usefulness, allowing you more versatility than the other classes offer.
This does come at the price of you being quite easy to kill and one of your supers being reliant on working with others to focus fire a target. So when deciding which of the three sub-classes are for you, you will need to take into consideration whether you want to be the damage dealer or the damage enabler.
