For professional scout, if an enemy killed a dear, can I take its corpse same as when I killed it myself?
Of course, it doesn’t matter who killed, but you won’t be able to lift the carcass of a wild boar, for example.
OK so why I see on twitch that people fight over a pack of deer to be the one who kills it first?
even before professional scouts, is it only to get the gold buff as rus or deny it from them?
Because in these games there is a Rus that receives a bounty and gold bonus from killing animals.
“is it only to get the gold buff as rus or deny it from them?” Yes.
