People joke about Icefrog following Reddit opinion in balance, but I think if a hero is clearly overpowered it's not hard for people to notice.

The next one theorically in the nerf list is Invoker. Will he be nerfed? I'm not sure… Dota 2 right now is very well balanced. Sure some heroes may stand out more but I don't think is nowhere close to, for example, jungle Lycan days.

Still, there is a gap between what Invoker can do in all phases of the game and how the hero escales and, say… Huskar.

Personally, as long as Storm Spirit and Tinker are out of the meta, I'm happy.
