Now, more onto the actual tips. OhieMitzen is absolutely correct when he told you to avoid staying in Hellfire Peninsula for too long. Sadly, this is quite indeed a beloved zone by wpvp-ers, since lowbies oftentimes go quest there and thus there are many people to farm. So, here's what I do:
I rush to complete as many quests as possible, in order to reach lvl 60 and obtain the flying skill. Depending on how terrible the ganking situation is:
-> I stay and quest near Honour Hold/Thrallmar if there are no gankers nearby;
-> I move to Temple of Telhamat/Falcon VVatch if there are some gankers camping the aforementioned zones;
-> I move to Zangarmarsh, if Hellfire Peninsula is a nightmare for questing.
That's the good thing about flying. VVhenever the questing experience becomes unbearable in one zone, you can swiftly move to another while also avoiding potential gankers.
For the sake of accuracy, I must admit that being in the air doesn't always mean that you are out of danger. Some classes can put DoTs on your and use parachutes (engineering)/levitate and not fall into their deaths, but that won't happen that often.
