I don't like warzone quitters, used to be a guild rule we never quit warzones. Now it's a recommended guideline.
I quit warzones when the people in them quit playing but stay in the warzone. I'd much rather have someone drop out of a match than sit there and suck or do nothing but complain and do nothing to help take the lead.
At least when the quitters quit you've got a chance of winning if the new guy isn't a quitter too.
Like you I don't like quitters but I've started quitting when we lose 2 nodes (CW and NC) and 2+ members of my team immediately camp our only node for defense medals even though its still possible to win.
