This can also be used to reuse a kritz multiple times, or you can drop other weapons. You can drop your demo another sticky full of 8 sticks when you're holding last and he can have 16 sticks + traps when the other team pushes
alto (RGL forums thread about this tech in highlander)some key facts -
-DR dropped weapons count as regular dropped weapons
-dropped weapons are fully loaded
-dropped weapons expire after 30 seconds without being picked up
-picking up a dropped weapon resets it’s 30 second timer
not only can a demo get 15 stickies on mid, if he wins the mid he can continue to juggle 2 launchers throughout the round, and with a 30 second lifespan on the dropped weapons it’s even possible to die and make it back before it fades. and even if it does, your spy can just do it again at any point later, and taking your spy out of the game for 10-20 seconds is arguably a small price to pay for a 2nd sticky if used correctly
you could take it to 11 and have your DR spy just fucking generate weapons with a dispenser during downtime
