>get punched in the face by the engineer since he cant remove the sapper anyways
why would the engi even care if his mini got sapped
better yet why would you sap and shoot a mini to begin with
This and if it's a level 3...stand on the opposite side of the sentry, sap, backpedal, shoot, profit.
Of course that's assuming your team doesn't exist, because even a scout can just bat it down at that point.
