I'm still undecided about how the latest patch helps but...

I pretty much agree with Micah about the root cause. It's not that the heims are completely unbalanced over the course of the game it's just that they have such an overwhelming early game strength that the vast majority of defenders have almost no chance against them. That aspect of their "play style" is simply not fun - no matter which side you are on.

You should always have a decent chance to at least fight off a rush nation.
