Agreed, while a title is honestly a little far fetched. A warzone lockout is a Great idea.
I can think of 1 habitual quitter off the top of my head, not only that they like to /emote rude things to the people who he thinks are bad. They quit the WZ, we either get handed a quick loss worth 40 wz comms or we end up winning. Only to find the same person in the ops group after we requed next game.
I have seen several games in Civial war that start out 6 vs. 8 and we control middle while both sides get capped when recoruses are at 590 (them) and 560 (us) they then flame the team for poor play then bail. On many occasions we end up winning because 3 players get added.
While the punishment for these types of players are naturally for their peers to openly point out that they are lame, an in game punishment is more fitting to spare the dedicated pvpers from this type of player.
