(2 Year Hiatus here): I regularly played Doc before I took a break and I distinctly recall getting notifications when Survivors are at Tier 3 madness and scream. Now the only time I get notifications is when I use static blast and they scream. Did they "nerf" Doc on his ability to track Survivors?
Edit: You guys are ignoring what I'm saying aside from the first person who responded. I was around for his rework. I mean specifically, I'm not getting survivor location notifications when survivors scream at Tier 3 Madness. The only time I get notifications is when they get hit with Static Blast. They aren't running Calm Spirit either. I'll hear them scream, but no location notification is given.
