For the whole debate of abusing the leveling system, I can guarantee you they won't fix it.

Don't know if yoshi said anything this time but there was a huge leveling issue near the end of 1.0 where Yoshi basically said Yolo. I got every class to 50 (cap then] in 2 days because of it. We almost all leveled that way. Thank you random uldah spiders.

This blu mage leveling method has been around forever now. I'd recommend spending the ... hour... it takes to level it.
