While I could be wrong, I'm guessing
this announcement of the new Alliance
race is an early April Fool's joke. Not just because the idea of a "wisp" race came completely out
of the blue, but because their racial abilities seem downright odd. My personal favorite has to be
treeform, which turns the wisp into a tree for 30 seconds. During this time, spirit is increased by 300 but the
wisp's chance to dodge or parry axes is reduced by 50%.
Edit: Eyonix claims this is "no joke" but I still think he's joking.
