Why would I do a quest that takes 10 minutes and yields 1500 exp, when I could do a PvP scenario that takes 10 minutes and yields 8000 or more exp, not to mention realm points.
You obviously exaggerating. 1500exp is the amount you would get for a PvE if you where around lvl 6. 8000 exp in a bg you would have to be about lvl 20+.
So you either have not played the game very much or at all or you are delutional.
