Thought of a change for the soda popper hype:
+when you run, you fill a meter that gives you extra jumps. you can use as many as you want in succession, but each one drains the meter (like a combination of Vaccinator and BFB meters)
-no built in double jump
So basically you will have the same playstyle of having huge spurts of mobility, but the weapon is now both more reliable and less annoying to play against, since scouts couldn't just avoid every rocket for 10 full seconds. At the same time, it now has an actual downside that after a fight you are much more helpless, and therefore cannot be as aggressive.
Wondering how many jumps should be available at maximum meter, and how quickly it should fill. I was thinking 6 maximum jumps, and fill in around 8 seconds.
