Normally, I couldn't care less who sees when one of my Strange weapons has ranked up, but, I've recently got a Strange Dead Ringer, and, whenever its rank increases, it notifies everyone on the current server, including my enemy team, that I'm using a Dead Ringer. Obviously, this is inconvenient when I'm feigning death, or going for "silent kills" (e.g. with the Spy-cicle or Your Eternal Reward).
Is there any way around this (i.e. can I stop these notifications going to everyone server-wide every time my Strange weapon ranks up)?
