Rogues and Hunters are very controlling classes with interupts, although the damage mightn't be as good as a lot of other classes the CC they provide are amazing. These aren't the classes you wanna engage an average twink 1v1 maybe a noob but not an average player to kill. Instead you want to assist stronger classes like ferals,monks,spriests with killing, they themselves don't have much CC but with your CC you can own it up like a bro.
Suggested gearing is a balanced setup with stam,crit and agi, alongside a defensive and controlling play style.
Rogues-engage when you know you have the highest chance on a kill,preferably healer or other targets.
Hunters- engage by first locating said healer, concussive shot on melee to peal and interupts/freeze traps on healers.
Happy hunting!!!
