How I deal with rogues.

Purge, Flame Shock Nova totems, rinse and repeat. Every rogue I come across is paranoid, they usually CloS and run away after they take any amount of damage. The idea of focus fire scares them. Thats all the attention I give them until they're the last DPS standing. They make life hard and if you worry about them or focus on them, you'll really pay for it.

Just heal through the damage and realize they're last on the priority list for a reason. Rogues only frustrate you by the amount of attention you give them. I had a rogue last night some in do some dmg and then CoS vanish 15 times in one match. A highly defensive team that didnt want the nuke. Talk about annoying.
