Nah, much better to queue at 4 am when there's only two ppl, win and run weekly BH. You can have TB the rest of the time for all I care.
If you are running it at 4am, there's a few scenarios here.
1. You are in a different country OR farther west in the USA.
Response: Completely understandable. I'd do the same if my faction couldn't keep it for the populus.
2. You work 2nd or 3rd shift and have some time to play.
Response: Yeah I know how that is. I worked 2nd for a long time and 3rd as well. Takes a toll on a man's body.
3. You are skipping your first two classes in the morning cause you are too hyped up on Mountain Dew and Cheetos because you want a chance at TB.
Response. Lol K.
4. You wake up early anyway due to work and having cats who just so happen to be hungry at 4 am. Go feed the felines, log in for a quick daily or two, and do TB if it's up.
EDIT: I've done TB a few times during the day. I guess alliance loses mostly because we love to bring players with no resil. The other day there was a healer screaming at people to keep him alive, and when I inspected he was in full pve firelands gear. So yeah, pretty easy to roflstomp people with zero resilience. Bloodhoof's alliance is all backwards: people go in full Ruthless gladiator to Firelands pugs, and in full firelands gear to Tol Barad. Sad but true.
