Defib may be buffed next season

I was playing the preview and I noticed that when shooting an enemy with a minigun from a good distance who was just defibbed, I dealt no damage. But maybe that was just spread on the minigun as I dont understand it yet, then later I am running sledge and someone is defibbed infront of me, I swing and they shoot a bullet at me before my attack hits which should cancel any i-frames, the sledge goes through them but no damage. However maybe thats just some server side issues as my mates also had some lag so maybe season 6 preview servers just werent the best, so then again later there is another enemy who was defibbed, I swing once, they shoot again which should cancel i-frames, my sledge goes through them but nothing, they are still shooting, and dealing damage so I swing again, before this it would have already ended even if they didnt shoot, but the sledge still goes through with no damage and they still had the defib white effect on them. Which confirms my suspicions. Now I know that the preview isnt the same patch as the release one, but still if it is an actual thing then its truly horrible. The defib i-frames were already quite annoying at times, but for it to last this long is truly horrible especially with them still being able to deal damage, it also makes the gadget cooldown less meaningful as there is less time they can actually be harmed before being able to use gadgets.
