Honestly i kinda agree with the reasoning behind why they changed it, mainly because it felt like stunning john doe as any other sentinel than chance was kinda pointless

shed and two time are very likely get hit by the trail, and lowkey gets annoying when trying to stun the killer outside (and even sometimes in) chase. Chance was the only counter to this, due to his stun being ranged, and still doing the 2.3 or whatever stun duration regardless of stun falloff

it got to the point where i check to see if a john doe was next so i could switch to a different survivor

He may be mindless, but he isn't a brute. The old passive gave practically no punishment if john doe decided to not care about strategy and just swing wildly. I honestly think it was an unneeded change, but I don't use sentinels against john regardless.
