Increase in the number of goblins and imps.

I don't understand why there is such resistance to cosmetic changes?
Necromancers were banned from Isra and Vidomina necro leveling - no one objected. Although it seems you could also trade necro on a non-Jebus not for -3k, but for -5-6k. The lower the starting bonuses, the more balanced the game. Well, and you won't have to hope that with Inferno or Stronghold you'll definitely get Gogs-Cerberi-Wolves, but calmly play with what comes.
Ideally, Luna-Galtran should be banned until the start of the second week for all castles except Conflux and Necromancer respectively. Otherwise, the match can easily be ruined often because one gets an OP hero, while the other at the same time struggles with his own forces.

Hmm, also ban Grindan, Labetha, Brissa, Daimer, basically everyone, they're all OP.

But seriously speaking, I think it's a good idea to increase the number of Imps; Goblins are no longer needed. The start for Inferno is often lousy and there's nothing to break through defenses with. And Stronghold is a different topic; there are many good heroes, you can start with Tyrax who is quite strong, with Tactics and a bunch of fast Wolves, or with Gunnisson, with a ballista he demolishes everything.

Banning any heroes besides Isra and Vidomina is, in my opinion, nonsense. Heroes is such a game where there are many "imbalances" and in the end daddies (pa-pas) rule; the game is balanced because of the number of these "imbalances."

I like Heroes just the way they are, only Inferno is much weaker than all other towns because there's nothing interesting in Inferno, the heroes are weak, the army is crappy, the respawn is often poor. That's why I support increasing the number of Imps.
