My reasoning behind this suggestiong is that full diamond players die everyday by invisibility players. Which isnt very fun. Getting all the way up to dia and then get killed by someone you cant see is kind of annoying. Really no one except people who do it thinks it should be in assassination. I bet that if you start a poll on whether or not to remove invisibility from assassination, it would probably get removed.
