Actually, I agree with TAKE' NOTES with this one, Storm Spirit either has to be remade perfectly or not at all.
And, there wont be two static grips, they're very different.
One is a channel, and you move to them, One is an active, were they move to you, and you are slowed in the process.
Im neutral on this, I just rather see the full storm spirit. But, I DO like your second skill, is synergies really well with his ult.
Thanks for the comments, and Yes there are differences between the two skills but they are really very close to the same thing and I've even heard people call it storm's grip before, that is why I don't want to put it in, plus the skill that is in place now is a combination of his purge attack and it stuns the unit. The main thing that is missing is the slow effect on SS which really didn't mean much if he had mana anyway, in my opinion, though if you couldn't blink out, then yes it did do alot.
