I would say hunters require great skill because the classes are focused around precision. Especially gunslinger, with golden gun and throwing knife requiring excelent accuracy. Plus, they have no panic subclasses. Titans have striker and defender, which gets them out of most situations as soon as the super is popped. Warlocks can throw a nova bomb at a threat or the ground to distract if not get an easy kill. Sunsinger can charge in with a shotty, probably get 1 kill, die, then resurect to kill almost everybody in the area. With landfall, stormtrance can be a danger close fail safe as well as a wide hitbax for the actual lightning. Hunters dont get those luxuries. Golden gun requires keen accuracy, as well as throwing knives. The power to 1 shot anything, but no shield and easy to miss. Bladedancer is about evasiveness, and the super may be a roaming super, but you require close precision because it can miss as well. Nightstalker can miss but you can still benefit, but hitting it is not only satisfying but also crucial to ending a super faster.
