"AFTER first blood OR the five minutes mark of the game. If any form of technical difficulty occurs prior to either of these conditions, then the game will be restarted."
First blood often doesn't happen until like 20 minutes into the game! But this doesn't mean that one team wasn't winning! What if 1 team had scored 2 dragons, and had invaded the enemy teams jungle repeatedly, etc etc etc, the game should not be restarted at this point.
The game should be restarted ONLY in the event that the game has been ongoing for less than 5 minutes, and first blood has not been scored.
