Skirmishers

Unlike Assassins, Skirmishers aim to shred through any nearby enemy that approaches. Because Skirmishers lack high-end burst damage or reliable ways of closing in on high-priority targets, they are instead armed with situationally powerful defensive tools to survive in the fray, along with extreme sustained damage to cut down even the most durable targets.

Lack high-end burst = more burst than assassins Lack gap closer = more range on than gap closers than assassins Situationally Powerful defensive tools = Godmode EXTREME sustained damage = extreme sustained damage
