For a character that only has to hit one spell to do whatever damage she does, it seems a little ridiculous to have a CC spell on par with a tanks. Does it REALLY need an area of effect trap which last for two seconds AFTER it MISSES you? Does that really seem fair?
Small Edit: Perhaps the reason it feels unfair is because it gets part of two worlds. Is the skill a skill shot or a trap? Traps don't trigger instantly when they hit someone. They're used to cut off routes of escape while skill shots don't stay after they're shot. Whats the intent of the skill? I believe it should just be a skill shot considering I rarely have used it as a means to cut off an opponent. You want to keep the circle? Go ahead, just don't make it linger like a trap. The player shouldn't be rewarded for missing.
