Little advice from a veteran. Get a friend. Load Q2DM1. Duel. Give it some time. Once you start understanding the map (it's not as immediate as it seem, far from it) and once you start learning the trick jumps I assure you, you'll have the best online experience of your life.
Well, I guess you all that came here for this game have played HoMM3. And this one is an hommage to it. At the beginning, I was super impressed with all of it, it felt like a modern version of HoMM. Then I played more, and got sad about how big of a wasted opportunity this game is. The city builind is severely lacking and uninteresting, the units are bland and not very varied (both in design and mechanics) and worst of all... there's a cap on how many units you can have in each slot. One of my favourite tactics in HoMM3 was playing as a necromancer and amassing MASSIVE armies of skeletons. It was OP? Hell yes. It was FUN AS FUCK? Also yes. Is this game fun? No.
