Before the CIS tournament, I played a match on the same mini-map where someone in Dragon Utopia got full control with a tea kettle on the second turn. There is nothing to counter that. Let's just ban control until 131, and then go completely old-school and play with a total ban on control. How does that sound? Resources and time are spent on every element of the game, whether it's a Mage Guild in Dragon Utopia or a Grail. I was amused by comments like "I'm too lazy to dig (learn), so let's ban it." If you don't know how to do something or you do it worse, that's your problem.
Nevertheless, I agree that the optimal way is to use it in a conference after building the Mage Guild.

Regarding Gosha, I have said repeatedly: until we try banning him, we won't understand anything, but the forum will be against it. There is a second option that I liked: programmatically make it so he always gets 1 stack.
Regarding Goflux, unbanning fairies and psychs, or choosing a hero—all together it would be too much. For Luna, as well as Izru + Vidu, programmatically ban the upgrade of Fire own-experience to the last level.
