As mentioned in the title, I've come across a number of players who enter PVP frontlines and just sit at spawn (occasionally moving their character a bit, but remaining generally afk) to just ride it through to get the exp.

In the last 10 matches, I've experienced this problem on my own team at least 4 times. While better chance than not, that's only accounting for the members of my own team and whether or not there are people on the other two teams with afkers as well.

The whole process is ruining the game type as well as allowing people to exploit the exp given.
