The market gardener deals critical hits during a rocket jump. Now the question is:
What if the rocket doesn't belong to the jumper?
So essentially what would happen is, an enemy soldier shoots at your feet, and you get launched a few feet in the air by his rocket. Now is this considered a rocket jump? In other words, will a successful hit with the market gardener result in a crit at this point?
Best Answer
Yes, the weapon would still crit.
Market Gardener considers you to be rocket jumping if you are airborne because of any explosion- including explosions from enemy explosive attacks. It still won't count other attacks which could knock you into the air, such as a Pyro's airblast.
The weapon demonstration for the Market Gardener shows a soldier launched into the air by an enemy Demoman's stickies causing a crit.
