Why is still allowed? It isn't even PVP, it's a very onesided rape that is over in 5 minutes and you have to sit in queue for another 20 minutes (to be raped again). To top it off you also receive 0 honor.
This stand especially true if you are soloqueueing, you lost the battle the second you pressed "join battle". There is ZERO chance of winning if you are a pug against a full marshal+ premade. Even 5 man premades are often enough to swing the tide in a pug battle and win, but the the victory wasn't given to you the second you entered but by actually fighting and securing key victories in the field.
