It just turns the game into pray and spray.Even then you have to hit someone with a large amount of your ammo before they die.
Being a spy is all about good acting
>see a spy disguised as a sniper with full health calling for a medicNOPE TOTALLY NOT A SPY
The biggest give away is you can't attack and the name above you.That sucks :(
Only good way to be a spy is to cloak into their base, then come out disguise going in the direction of the team.If they see someone that looks like them running the same direction they wont notice stuff.Ive gotten a 10 kill streak doing that
The best thing is to use the cloak and dagger for it, honestly.
