Just curious as to why I've seen rank 30's queuing into the 40's bracket. Is 50 bracket that bad?

Some r30's I've been asking say it's because they're farming points but to me it seems they like to farm the bad players that just start PvP. Maybe a steady rate is better than losing some in 50 bracket?

I'm just curious because I'm grinding hard to get to rank 30 and I don't want to do it just to play in 40's all day.
