pazerpeople are way too worried about this
it's unbanned in HL (yet nobody uses it because the ubersaw) and spies also have access to health pool info, and it makes very little difference to the game because most of that information is already implicit with > silver level gamesense
Though I don't really mind the solemn vow unban that much your argument doesn't work for 6s
HL is a clusterfuck. More people on the enemy team + messy comms from 9 people make having a med maincaller that can call 1 person's health each time less valuable
Having a spy to call hp doesn't apply to 6s
