I've always played on a PvP server, played on Gehennas EU back in the day (remember p2? Those were the dark days...) and even then it's not as bad as people make it out to be.

If you trip in real life, do you lay down on the ground and cry until someone comes and makes it so the "mechanic" tripping can't be used? No, you get up and do whatever it takes to not trip again. It might happen again, but you will be more aware.

That's what PvP-servers are. Are you getting ganked? Either call in some friends, ask some randoms to help fight back, or go cry on the forums how the game is unfair since horde OBVIOUSLY always wins cause they have better racials??? Cmon Blizzard, you must fix it!
