As a disclaimer, I'm not very fond of his current Cyclone Heroic. I feel it doesn't seem original enough. Any Idea's?

While I appreciate anyone who also shares a vision for a Pokemon-based MOBA, I'm afraid you may have overlooked the main point of Heroes of the Storm by BLIZZARD ENTERTAINMENT.

A way to counter this would be to have it work more like Alarak's Right of Rak'Shir or by reducing the Unkillable status to just a few seconds upon receiving lethal damage.

I've been thinking about what you said about his W (Undertow), and I agree that it could use some tweaking. However, the time reduction could mess with pathing and his Level 7 The Bends talent, so instead I'm considering increasing the cooldown slightly and adding a 0.75 second delay to the cast, giving enemies time to react and move out of the way. I'm also thinking of redoing the Riptide talent to be less spam-able. Which of the following sounds better: Undertow can be recast once for free...

Not quite what I meant, I thought of having it act like a stream, where if part of it hits terrain it will cut off there but the parts of it that don't will keep moving. But in retrospect I think you're right, that could really limit it's uses in tight area's where team fights usually occur, plus adding such a dynamic to it's pathing could be taxing on the game's engine.

A cool idea. Well balanced, simple to understand while still unique. My only real suggestion it that the cooldown and mana cost on ARCHMAGE's active effect are a bit extreme. It's not as broken as you think it is, at least in it's base form.

Actually, a lot of the supports have some level of Dispacement, but it's usually more for Peeling. I'm actually a little worried that I overdid it with having so many displacement abilities on a single character, as it may make them broken it team fights (you know, HotS whole selling point).

The way Kilrog's trait is now, making him unkillable to all but one target, is in my personal opinion, not a good idea. At all. While Kilrog's lower than average stats and other features do help in balancing out the benefits of the trait, it also means that the selected target is going to have to babysit Kilrog for the entire match in order to stop him from snowballing forts and skirmishes. It would suck the fun out of the experience for the unfortunate player by forcing them to constantly...

Idea: Rocket Launcher and Concussive Blast are skillshots while Grounded, Area of Effect while Airborne.

Why not make it so she can't take off while below 20 fuel? Just word it like so: "Hover can not be activated while below 20 fuel."
