that wasn't a lag switch, just lag. .he was the host. with a lag switch you will get connection interruption every time the player uses it, usually while you are shooting him, or someone else is.
There is a special ring in Hell for lag switchers/glitchers.
Dont mistake a Lag switch with bad connection....but using a Lag switch is illegal!!!!
It would be nice to see the software engineers put some type of lag response in a future update.
For example: If an individual lags to many times, or a certain duration, boot the player causing network interference. Have it make a log. If it continues, cause a rest time (say 5 mins) before they could enter a new match.
It will either drive that person to get better internet and not interrupt others game play or put a stop to the use of such devices.
If if comes with a inconvenience to the cheater, they will stop! Reporting seems to do nothing when most of the time it is a bunch of people whining they got owned by a better player.
Youtube shows great examples of someone using one for future reference!
