you can kinda get 1 air pogo on junkrat
the game has several methods of advanced movement spread out through heroes- lucio can climb anything with his wallride, genji has double jumps + wallclimbs, junkrat has his sticky thing, etc
with junkrat if u place your first sticky, wait the 8 second cooldown, detonate throw another one slightly above eye level immediately detonate, you'll get knocked way high in the air and can kinda strafe to get significantly further than you would have gotten with one sticky. it's not an impressive distance, but it's an important distance
