Season 14 introduces the new Blowpipe into the Armory with a range of powerful darts for use.
In this launch implementation the difference between the Hipfire and Aim Down Sights effects are much too similar and as a result create an overpowered Hipfire experience. The team are iterating on this experience and will be reducing the effectiveness of Hipfire in a coming update.
Update: Blowpipe quickfire has been rebalanced in 3.2.1
