No tournament will ever support heroes; never!
I don't think that's entirely true; it just needs to be addressed. There are small leagues where, in addition to the main games, there are many secondary ones. They are all built on the principle of "the more players (see website traffic), the better," and no one will refuse a couple of extra thousand users who boost their website's metrics. Besides, introducing a new discipline won't be difficult from a programming standpoint.
Realize the reality. Only through your own efforts, with a bunch of restrictions, with rules that are a mile long, and so on.
It's not that complicated if you think about it.
