Truth, what it is is say you get a bit of lag, it counts the total seconds your plant took fire, even if you blew up.
To me honestly, it doesnt bother me because if i hear 2-3 seconds of me being owned" after back in tower, i know someone hit me up , and hard too.
If you tower without hearing so much as a bullet strike, you got owned hard.
If you hear a few seconds of gunfire after tower, you know you still got powned, but at least you lasted a few miliseconds more before you blew up.
