Nope, and you gain exp in warfronts almost entirely to prevent exactly what you're trying to do. Twinking has always been a blight in games that allow it.
I wasn't going to touch it but since you brought it up, I agree. Leveling warfronts are supposed to be a fun distraction and a break from everything else you might have going on. When you get people who just pick a level and try to gear to the max at that level and then run around abusing the **** out of your casual leveler, it defeats the purpose. And we all know exactly what happened to the twinks in WoW when they added the option to turn of xp gain and forced those with xp gains turned off to fight other twinks...the "no xp" BGs died. The people who swore up and down that they twinked for the challenge of fighting other twinks suddenly lost interest.
