There is always going to be one guy after another. It usually ends up that you will get more than just you and the other guy that you are fighting, you will have some guy win his 1v1 and come in a pick the guys fighting. Always be ready for that. I always say somthing before I get into a fight with more that two, were I have the advantage.
When TOC was going on, that was the best fights I've had in KOTH. They tried more to get involved in 1v1 then get into some other fight, and I remeber that Bruv did that a couple of times wile I was fighting. Also, after I win the fight and go to a fight that I don't want to interrupt, I bring back the RPMs, so that you can conserve fuel, and try and let them finish it out. Usually, I still get there before they are finished, but somtimes there is nothing you can do.
I'm pretty sure that you know this, but HOing isn't realy nice and most players don't like it. I would try not to HO most of the time, unless it's an angle that you think that he couldn't take. I would try and take every advantage I could take, other than a HO.
