Drugflash? No thank you.

Spies with less defense? No thank you to that as well.

5 second delay is too long for a spy, currently there is a delay (shorter than 5 seconds for sure but still long enough to die if you've been taking damage + latency issues)

I'm with netphreak on this issue, make some kind of progress with runspeed and see what happens. If you cripple a spy by shooting his legs then he shouldn't get away stealthed or not.
