Currently, LFR offers nothing for me, and I assume many others. And those who have started the Black Prince rep, will know about the 6000 valor quest. So here's what I am doing.
Enter LFR, follow the group during trash, cast a couple of spells just to pass the time, then AFK for the boss fights. Collect valor and gold/shards from gear and queue up for the next one. I guess I should say thanks to the few who actually bother to take part in boss kills, appreciate it, keep up the good work. Meanwhile I get to catch up on some TV shows I've recorded on my TiVo.
Just out of interest, I am wondering how many people are doing a similar thing, I notice people AFK all the time, usually healers. I know i'm not alone, and no, I don't feel "guilty", I got tired of boosting people long ago, I think it's only fair I let other people do the work for once.
And you are a douchebag, abusing the system and other players. When I see people like you I make sure to get them kicked. You're wasting our time. Stop playing the game.
