This!!! +1 , I crouch and spam revive, but get no revive. It is absolutely wrecking my k/d trying to complete the Sabotage support challenge when only 1 out of 10 revive spams work...
Apparently its been fixed with "Nov 19 changes"
After changes to the Defibrillators in Update 1.1.2.0 made them more demanding in terms of accuracy and target range, we've published a backend update to bring their usability back in line with our original intentions. We've increased their effective hit-boxes and range, which should make Defibrillators feel more consistent with previous gameplay.
Same thing today also. Defibs just don't work anymore. You need to drag revive people.
I worked perfectly before the update and now there's little hope of rezzing people up anymore
