All of you guys hating on campers. What gives? Are you that short sighted? Who does a rusher rush against? Defensive players. It's defensive players that you can flank around. It's defensive players that do not have the mobility to do much more than stay put, i.e. become targets. If *everyone* rushed with marathon 100% of the time, the game would be completely random and chaotic. There would be no strategy, just randomly running into people and hoping your connection to the host is better than the other guys, so you can win the gun fight.
Campers are the targets of rushers. Encourage them. They are where you get your kills.
BTW, without marathon, after the initial sprint you can only run 4 steps before having to walk to recover. With the size of maps in Ghosts, is it no wonder people find a defensible spot and park themselves there? Or do you think walking around, literally walking, out in the open is a viable strategy?
