First thing i noticed
umm...where did the other three points go?
Besides that its almost useless, for a mage unless you have multiple people on you, you shouldn't blink when an enemy will be able to hit you. In other words, if you just blinked your probably not going to get hit anyways so why do you need less chance to be hit?
And W.E > imp blink. No matter what imp blink may be
Unless maybe someting like range increase, or cooldown decrease. Even than still maybe.
