Your attitude is pretty shitty. As for "time-efficient" no, it's called lazy, you get more exp from flying around and actually taking part in killing mobs. As for "96% of the playerbase" I call bullshit on that because I've done invasions on 5 different server clusters and not one of them had a mass amount of AFKers, most of them flew around in packs to hunt elites/bosses.
He's my comment for relevance sake, you're lazy. Get over it and do BGs or don't do them. You don't -NEED- the transmog, you want it. So If you want it, put in the effort to get it. Your whole thread and replies are basically "I'm lazy and I just want stuff handed to me, just like how I afked to level."
