The ability is OK.
At least doenst kill you a model, like the Cons flare.
abilities are debated by how many models they driectly kill when its activated? You really compare abilities which opens the half of the map other wherever you click cheap and for long time with a flare its activated when only you step on it?
At least you can sweep them right? Maybe hard/easy but there is an option.
Im talking about it has no counter. If cons flare broken it can be debated that doesnt mean others are must be fine.
