I believe we've already decided which stats the gun should have (the obvious), but how would the player decide which dart he would use? (If darts are to be used as the weapon already seems pretty balanced)

Would the be a HUD? An animation? One dart per life? It's confusing and I'd like that to be clarified.

Also some of the Darts are a bit ambiguous, as in what would be the difference between Barbed and Poison? What would the Tranquilizer, Midas and Cyro Darts do? If the Transmitter one already deals mini-crits, what's the use of Jarate? And would Taser be like the Razorback?
