doesn't sounds like Faernal. Sounds more like a desynch to me. It's rare but it happens.

If in fact a player knowingly prolongs a game out of spite, that is unacceptable.  Did he chat at all during this period?  In any event, it would be uncharacteristic for him to pull such a stunt, but it's hard to chastise someone for one incident.  If it turns out to be a pattern, then folks might consider not putting him in games.  But everyone has "off" episodes, and if someone gives assurances they "won't do it again", I would give them a pass (at least until they do it again).

My guess it was isolated situation.  Ask him about it, or get a response from him before out and out labeling him a griefer.

I call this type of behavior for zooming.
coz zoomer.
I hate zoomer.

Faernal has dragged out games in the past....he does it to troll, for the "shits and giggles" of leveling his titan with noobish attacks and such...it isn't common but he does do it, especially when he feels the other team needs to "earn" their victory...

One game every once in awhile is annoying....nearly every game (like zoomers and kbroke back in the day) is a true problem....

Of course, things have changed...ICO has more new blood so the question is:  how much affect does one troll still have? 

Add Archa-Ra and RedTank to the list of non-quitters.  I  had planned to just let my Sins run in the background until they either "won" the game (after the players on the winning team had either left or stopped playing) or they quit, but it minidumped while I was playing Unreal Tournament (lol, big surprise).
