For context, before this patch, if you tried to use Counterspell on Hotel Guest's initial grab, it would run out before the cast duration ended and send you in regardless
It seems like they fixed this interaction with the introduction of Indomitable, as that item likely had the same issue, which gave them reason to fix it, and that fixed Counterspell too!
(This does mean Doorman basically got a shadow-nerf this patch, as this fix is not documented anywhere as far as I can tell. But I'm fine with it because this is how it should've worked in the first place)
Tl;dr, Counterspell is an even stronger counter against Doorman now
And for the Doorman mains: I'm so sorry, good luck getting any value with your ult now, I'm moving onto Holliday until they fix him lmao
