78 to 80

Okay....I just hit the lvl 78 wall. I am soo close to 80, however, I havent had the time to put in lately to make Dungeons a viable option. So I have spent the last week or 2 just logging on and PVPing. Anyone in sight. If you are opsoing faction and I see you...It is on...That being said. Would you say questing is still the best option or should I make time for Dungeons so I am not side tracked by passing Horde(Sorry horde)

If you have a good group who can blow through the dungeons fast that might be a good option, but questing is usually the best and fastest way since it's solo.
