Is there any character too big for Heroes of the Storm?

The header image (it will be familiar to you if you’re active on the Heroes of the Storm subreddit) purports to show the various Heroes from Heroes of the Storm to scale. I have some issues with it — I don’t believe Cho’gall is even close to that big, for example — and it doesn’t include newer characters like Ragnaros, who I believe would be a lot bigger than Azmodan.But it still gives you an idea of just how massive some of these characters are in their native games.

And this has me wondering if we’re too quick to dismiss certain characters as options for future Heroes of the Storm contenders. Sure, Deathwing would be massive, but look how big that ODIN is. You could just as easily have Deathwing in his Human form. His Ult could be the ability to transform into gigantic Dragon Aspect form and step on people, just like Tychus calling down the ODIN.

So what do you think? Could we have Alexstrasza or a (playable) Ultralisk in Heroes?
