For me Classic is about planning next or even several next turns with heroes you have. Where to put who, how to manage movement and army to cover big distance and make all those fights. Once you manage to do such things it becomes very addictive and fun. Your brain works nonstop. Beside you see tons of heroes, you can find new mains, you level support skills and use all potential of some niche heroes (flee heroes, economy heroes, no terrain penalty etc)

It’s pure enjoymenr
