If all servers ran FF-ON, your own team would be more dangerous to you than the enemy would.
Let's see, pick up an average Titan round.
-Tank fires at the wrong person. 1 TK.
-Teammate sprays Voss on dueling knifers. 1 TK.
-The inevitable problem where someone conveniently walks into your line of fire. 1 TK.
-Oops! You forgot your sentry gun at silo four. 2 TKs.
-Your motion mines flew for an enemy but hit a friendly passing Jeep. 2 TKs.
-The Titan attack begins with people hugging consoles 1 and 2. 6 TKs.
-Nade spam without warning. 3 TKs.
-Enemy walks into the APM your teammate was next to. 1 TK.
-Sentry gun in front of sentry gun. Counts as 1 TK, pretty much.
-Reactor core access. 3 TKs per full RDX group detonation. From full hull to zero, that makes about five detonations, thus 15 TKs.
Therefore, we can assume that the average number of TKs on the average FF-ON Titan server is: thirty-three. Let me stress that this is a purely theoretical number and that, in practice, it will be much, much higher.
