Heroes with the required skill.

I'm sorry, but why are you making a distinction between online and offline? You should pay attention to the section where you placed the topic. And in that case, what does your recognition or non-recognition of a particular hero have to do with offline play? Heroes with their specialties and secondary skills don't require anyone's recognition. In my opinion, you need to systematize them better. After all, you are preparing a cheat sheet for all games in general, or am I mistaken?
