Apparently you can use the experience given by invoking to level yourself in PvP. However, what this means is that if you are level 19, 29, 39, ect., it is possibly to invoke and level out of your designated PvP level bracket instance. I was able to get full level 20 gear and a mount on my new character before going into PvP. I was already close to level 20, so when I invoked upon getting there, my character became level 20, and suddenly I was the only one in the PvP match with a mount as well as level 20 gear, 3 skill points in one skill, ect. (I ended up leaving the match halfway through though since I had to go, but since I didn't want to get a "bug abused" win if this is indeed a bug which I would assume it is.)
Just a small issue that could find its way into a rare PvP match. However, it was still not a very steep advantage as anticipated. The real abusive advantage was having the capability to use the mount in a match where no one else could. The extra skill point/stats/gear didn't seem to give too much of an advantage, but seeing as I was already using significantly better gear/enchants than anyone at that level already, it would be hard to gauge.
