It's not about better or worse here. WOT is definitely more convenient. But Heroes = SOD. IMHO.
Periodically, on Heroes resources, some guy (who has played SOD at home for 9 years) pops up and shouts, "Let's play, I'm a father with many years of experience." Someone starts playing with him, and then this guy writes, "Nah, this isn't Heroes: the opponent takes 10 minutes of real time to make a move, what can you do in the first week? Who plays real Heroes and not this grind/cheating (choose one)?"
