wtf man.

how effective would that 10% jump be?

10% higest jump?

yeah but how effective would it be? Demo and Soldeir and Scout can already get pass their jump hieght limit....so only the Spy,Medic,Engi would benefit? and in the end only the Medic would realy benefit because its the one staying around the Heavy? Oh and i guess pyro but what Pyro would be staying around a Heavy just for a little jump boost? Pyro like spyr would be going around the battlefield burning or putting out flames?

no

This would be a situational weapon.
