Ideas and suggestions.

I also have some thoughts about Damage Dealers and Transporters...

I hope you're talking about translating them into the correct schools of magic? ;)

The new Damage Dealer mechanic saves 100 Mana Points due to auto-attack, but this is also a drawback when you jump into the darkness unnoticed

Regarding the heroes: Jeremy is overpowered - he has a Log and a Cannon from the start, which normally cost 5000. He has become the absolutely best hero in the game, in my opinion.
Ghoshan with the nerfed Necropolis is no longer overpowered, + the symbol of the Necropolis Castle, I would bring it back, considering the worthy competitors in the form of Igry and Vidomina

Consa and a bunch of resources also have the same value. Redwait's hat and the blue cap too.

So fix it, what's stopping you?))
