Lower hero radius

Lowering the hero radius by a few tiles to make it harder to lure and isolate them, would solve a couple problems that I've noticed.

1) It would add a buff to defenses for higher levels and hopefully fix some of the issues with cheap shields and such. If offense and defense is more balanced, there would be less incentive to get a shield or exploit fluffy bunny.
2) Give more flexibility to base designs

Heck no. Right now there's a trade-off, in that you either use up valuable real estate in center, or leave your heros more vulnerable. Make it impossible to pull them, and attacks will die horribly. Bad enough that everyone in creation embeds their CC in center and then fills it with wizards or a drag. You can't win if you can't pull. They already nerfed rage by 10%.
