@toxicGirl answer is very good and i appreciate the feedback from her. ❤️
I dont think that a good player would complain.. there are lots of players that are beginners in this mode, of course they will complain when something happens..but if you pay attention at the chat, zombies around you, have basic game sense, i don't think is that hard to avoid that situation.
Also, the message in chat that is not that common, usually its in hud and its not noticeable..that should help a lot. it was way harder without it.
If you stay hidden, in one place, of course they will target with grenade, but you also have antidote..so from my perspective its even.
I'm waiting for more feedback from other admins/players/vips
