Guys, I would just like to apologize for being so aggressive at first, and to you specifically Ginchy. Your reply wasn't quite as aggressive as I thought at 12 o'clock in the morning. I worked the night shift a few days ago and sleep has definitely not caught me up with the rest of the online community. At any rate I get almost bipolar in those late hours and again I'm sorry.
I'm glad that many of you found my trick useful. As you can see it can be used in PvP and the water doesn't have to be that deep. Take many parts of Zangarmarsh for example. The medium depth pools like outside Cenarion Refuge are quite good for this trick.
And it appears Skunk5 was able to pull a friend through to underneath Northrend in correlation with that exploit. So it's not quite so useless, but if you find it that way, don't use it. I just thought it'd be helpful most especially on any quests that require you to kill mobs that swim at the bottom of water.
